Introduction: State concisely the study's purpose and rationale. Present only the background, supported by a limited number of pertinent references necessary for the reader to understand why the study was conducted. Do not include study data or conclusions. Materials and Methods: Describe briefly, but in sufficient detail to permit others to replicate the study, its plan, patients, experimental animals or other species, materials, and controls; methods and procedures; and statistical method(s) employed. Institutional Review Board (IRB) issues are to be addressed here as stated under "Human and nonhuman experimentation" in the Editorial Policies section above. If the study was exempt from IRB approval, provide an explanation in this section. Results: This section includes detailed findings and must cite, in numerical order, all tables and/or figures, which should supplement, not reiterate, the text. Emphasize only the most important observations. Reserve any comparisons with others' observations for the Comment section (see below) Structured Discussion/Comment: Do not repeat the details of data presented under Results or present any new data here. Required headings include: 1. Principal Findings - a brief statement of the principal findings, limiting claims to those strictly supported by the data, avoiding speculation and overgeneralization. Give equal emphasis to positive and negative findings of equal scientific merit. 2. Results - in the context of what is known 3. Clinical Implications - the meaning of the study; eg, hypothesized mechanisms that might explain the outcomes observed and/or the implications for clinicians or policy makers. Indicate whether additional research is required before the information can be confidently used in clinical settings. 4. Research Implications - Unanswered questions; proposals for future research. 5. Strengths and Limitations - Strengths and weaknesses of the study, both intrinsically and in relation to other studies, particularly any differences in results. 6. Conclusions

Reviews

Reviews are solicited by the editors. Spontaneous submissions are not considered for publication.

Clinical Opinion

A Clinical Opinion paper presents a balanced, evidence-based discussion of a clinical issue pertinent to obstetricians and gynecologists. The paper may address an emerging or controversial topic or bring attention to a topic of increasing clinical significance. Opinions rendered must be based on an interpretation of available evidence.

Not appropriate for this category: 1) a review of an extensively researched subject. Submit as a Systematic Review. 2) an essay about issues for which minimal data exist, such as certain clinical, ethical, educational, practice, and research issues. Submit as a Viewpoint paper.

A Clinical Opinion paper is limited to 3000 words of main text (not counting the title page, abstract, condensation, acknowledgments, references, tables, legends, and figures). An unstructured abstract (1 paragraph; no headings) of no more than 350 words and as many alphabetized key words or short phrases as needed for indexing must be provided.

Subheadings to separate and identify sections of the text should be unique to the topic; the 4 prescribed categories required for research articles do not apply. To prevent such subheadings from occupying many lines on a page, they should be as short as possible, not exceeding approximately 6 words and preferably 1 to 4 words.

Case Report

Case reports should be written in accordance with the CARE guidelines http://www.care-statement.org. Papers should not exceed 1500 words, 20 references and 5 figures or tables. An abstract of no more than 250 words should also be included.

Editorials

Editorials are written or solicited by the editors. Spontaneous submissions are not considered for publication.

Images in Obstetrics; Images in Gynecology

IMAGES presents the opportunity to share an interesting, high-quality image related to obstetrics and gynecology and women's health. Priority will be given to those images of particular interest and quality, and those that provide the reader with key learning points to aid their practices. Up to 5 images may be included that exemplify the condition or case. One will be chosen for the print publication, and all will be published in full in the official on-line publication. Both Journal versions will include a legend, not to exceed 150 words. No condensation or abstract will be published. Supplementary material may include video. IMAGES should include: 1) A title 2) No more than 3 authors 3) Refer to AJOG website for guidelines on submission of figures, to ensure high resolution and quality. 4) Figures should be appropriately labeled with arrows identifying structures 5) Any information that might identify the patient in the figure must be removed (including acquisition date). 6) If the patient is potentially identifiable from the image, authors must have obtained written permission from the patient. The author is responsible for filing this in a secure location. The scope of the consent should allow the author to explicitly disclose the information to Elsevier and for Elsevier to republish the information in print and electronic format including journal web and social media sites. Authors must attest to having obtained written consent upon submission of the Images piece and must be prepared to provide this documentation upon the editors' request. 7) A legend up to 150 words that summarizes succinctly, as appropriate, the clinical information including presentation, evaluation (including surgical findings), treatment, and follow-up status . The legend should explain all labeled structures. 8) No references are permitted. 9) If a video is included, please submit a high-resolution still image. Submissions will be reviewed by a team of Editors and their decision to accept or reject will be final.

Ethics of the Editorial Process

If a report by any or all of the same author(s) has previously been published or is currently under preparation that deals with the same subjects, animals, or laboratory experiments, and deals with a similar subject as the submitted manuscript, the author(s) are to inform the editors in a cover letter about the similarities and differences of the reports. The editors may request that you upload such reports before further review. This requirement also applies to manuscripts in which subjects, animals, laboratory experiments, or data have been added to those reported previously. Please ensure that the final manuscript includes references for pertinent articles published prior to the publication of the AJOG Global Reports paper.

Submission of an article implies that the work (including manuscript, figures, video clips, etc) described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see https://www.elsevier.com/postingpolicy), that it is not currently under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder. Work that is already publically available in a substantially similar form (such as in the form of blogs, YouTube videos, etc) will not be considered for publication in AJOG Global Reports under usual circumstances.

All submissions are subject to review with iThenticate Professional Plagiarism Prevention. http://www.ithenticate.com.

All policies of the AJOG Global Reports also apply to abstracts presented at Society Meetings that are published in this Journal as a result of the proceeding. Allegations of scientific misconduct and breaches of the ethical conduct of research will be assessed by the Editors and referred to the sponsoring Institution for review, inquiry, and/or investigation, and disposition. Examples of inappropriate acts include but are not limited to: fabrication, falsification, plagiarism, repetitive publication, obfuscation of significant research results, violating requirements for experimentation with human subjects or animals, failing to comply with authorship requirements and failing to report significant conflicts of interest. Honest mistakes and differences of opinion about experimental design or interpretation of results do not represent inappropriate acts. AJOG Global Reports will make decisions about retraction of published work or other actions (such as sanctions) based upon evaluation of the information provided by the Institution and other information available to the Journal. Authors will be asked to identify the sponsoring Institution(s) which is responsible for the integrity of the scientific work and compliance with the regulations to protect human subjects and animals from research risk(s). When the research is sponsored from multiple Institutions, authors will be asked to identify the Institution which will take the lead in handling a potential allegation.

Human and Nonhuman Experimentation

Authors must follow the ethical standards for human experimentation established in the Declaration of Helsinki (World Medical Association Declaration of Helsinki: recommendations guiding physicians in biomedical research involving human subjects. JAMA 1997;277:925-6). The editors assume that a manuscript emanating from an institution is submitted with the approval of the requisite authority. The authors of reports of human experimentation that require local institutional approval must have obtained this approval before the experiment was started; upon request of the Journal editors, the author(s) must provide copies of the appropriate documentation. Institutional approval must be indicated in the Materials and Methods section of the submitted manuscript. If the study is exempt from Institutional Review Board approval, an explanation must be provided under Materials and Methods.

For reports of experiments on nonhuman animals or other species, authors must state under materials and methods that the guidelines for the care and use of the animals approved by the local institution were followed. The type(s) of nonhuman animals or other species used in an investigation must be named in the title, abstract, key words, and materials and methods sections of the manuscript.

For Images in Ob/Gyn or similar reports in which the identity of the patient is potentially identifiable, authors must have obtained written permission from the patient(s) on whom the report is based. The author is responsible for filing this in a secure location. The scope of the consent should allow the author to explicitly disclose the information to Elsevier and for Elsevier to republish the information in print and electronic format including journal web and social media sites. Authors must attest to having obtained written consent in the manuscript and must be prepared to provide this documentation upon the editors' request.

All research studies, including those involving patients, patient records, research participants or databases, require ethics committee approval (or documented exemption from the Human Subjects Committee) and informed consent (or documented waiver of consent), both of which must be documented in the paper. Studies on patients, patient records, or volunteers require ethics committee approval and informed consent, both of which must be documented in the paper.

Trial and Research Guidelines

Authors must adhere to the following guidelines when formulating the study.

• Randomized controlled trial.
• All Randomized Clinical Trials require registration with clinicaltrials.gov (or other registered authority), prior to enrollment. On the manuscript title page include the: 1) Date of registration, 2) Date of initial participant enrollment, 3) Clinical trial identification number, and 4) URL of the registration site.

• Health economics. In addition to the general instructions for authors and other guidelines applicable to the study reported in a submitted manuscript (eg, CONSORT guidelines for a randomized controlled trial; see above), authors of health economics manuscripts should consider certain issues specific to such studies and address them in the manuscript and/or submission letter. The checklist specific to this topic must be completed and included with the general submission checklist. https://www.elsevier.com/__data/promis_misc/ajoghealth.pdf

Translational Science

The only type of non-clinical research considered must be translational in nature and contain biological implications for obstetrics and gynecology. Additionally, the direct clinical relevance of every submission is considered when an editorial decision is made. Basic science without direct clinical relevance will not be considered.

As many definitions of basic and translational science abound, please see the following translational science examples to assist you in differentiating study types. If uncertain, authors may email an abstract to either editorial office with an inquiry as to whether or not the submission is encouraged; however, this does not guarantee acceptance.

Translational science examples:

1. Ectopic Pregnancy
• Clinical Study: an observational cohort study which shows that patients with a subnormal increase in hCG maternal serum concentration are at increased risk for ectopic pregnancy. [Encouraged submission]
• Translational Science (bench to bedside): proteomic analysis of maternal plasma shows differentially-expressed proteins in patients with ectopic vs. normal pregnancy. Or, an experiment in which the fallopian tubes are ligated in pregnant animals and hCG determinations are measured in maternal serum. [Encouraged submission]
Translational Science (bedside to community): analysis of techniques to enhance the adoption of best practices in caring for women with ectopic pregnancy [Encouraged submission]
• Basic Science: a description of the glycosylation of protein structure of hCG (even if it is based on the purification of hCG from patients with ectopic pregnancies). [DISCOURAGED submission]
2. Preterm Birth
• Clinical Study: an observational study in which a particular biomarker measured in the mid-trimester increases or decreases the risk for spontaneous preterm labor and delivery. [Encouraged submission]
• Translational Science: the transcriptome, proteome, genome, or metabolome of patients who subsequently have spontaneous preterm labor and delivery. [Encouraged submission]
• Basic Science: protein sequence of a particular biomarker. [DISCOURAGED submission]

Conflict of Interest Statement

Authors of all submissions must include a conflict of interest statement.

Disclosures must include any financial interest present within the past three years with commercial entities that are marketing or developing products (drugs, devices, diagnostic tools, etc.) related to the subject matter of the manuscript. Disclosures include, but are not limited to: stocks or shares, equity, employment, advisory or scientific board, grant funding, speaker's bureau, paid travel, consulting status, and honoraria. The monetary value of any such stock holdings should be named. No policy could cover every contingency that might be construed as a conflict of interest. Therefore, it is expected that should any potential conflict of interest exist, the authors have revealed this to the editors. All relevant conflicts of interest and sources of funding should be included on the title page of the manuscript at the time of submission under the headings "Conflicts of Interest" and "Source of Funding" which will be published with the article. If the authors report no conflict, a statement of this will be published with the article. Failure to report disclosures may result in sanctions. Use as much or as little detail as appropriate.

Examples:
• The authors report no conflict of interest.
• R.J.X, M.F., and L.Y.V.R. are employed by the Curette Company, Worthingham, MI. The remaining authors report no conflict of interest.
• R.H. received research funding from PharmaCo, San Antonio, TX, for participating in a multicenter drug trial in 2011-12 S.B. reports no conflict of interest.
• This research was funded, in part, by a grant from the OxyContin Association (A.R.Z.).
• A.E.B. was on the Speaker's Bureau for PharmaCo in 2012.

Manuscripts written or developed by anyone other than the listed authors should name those individuals in the Acknowledgment(s) section and state their relationship to any commercial enterprise.

Submission declaration

Submission of an article implies that the work described has not been published previously (except in the form of an abstract, a published lecture or academic thesis, see 'Multiple, redundant or concurrent publication' for more information), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder.

Preprints

Please note that preprints can be shared anywhere at any time, in line with Elsevier's sharing policy. Sharing your preprints e.g. on a preprint server will not count as prior publication (see 'Multiple, redundant or concurrent publication' for more information).

Use of inclusive language

Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Content should make no assumptions about the beliefs or commitments of any reader; contain nothing which might imply that one individual is superior to another on the grounds of age, gender, race, ethnicity, culture, sexual orientation, disability or health condition; and use inclusive language throughout. Authors should ensure that writing is free from bias, stereotypes, slang, reference to dominant culture and/or cultural assumptions. We advise to seek gender neutrality by using plural nouns ("clinicians, patients/clients") as default/wherever possible to avoid using "he, she," or "he/she." We recommend avoiding the use of descriptors that refer to personal attributes such as age, gender, race, ethnicity, culture, sexual orientation, disability or health condition unless they are relevant and valid. When coding terminology is used, we recommend to avoid offensive or exclusionary terms such as "master", "slave", "blacklist" and "whitelist". We suggest using alternatives that are more appropriate and (self-) explanatory such as "primary", "secondary", "blocklist" and "allowlist". These guidelines are meant as a point of reference to help identify appropriate language but are by no means exhaustive or definitive.

Author contributions

For transparency, we encourage authors to submit an author statement file outlining their individual contributions to the paper using the relevant CRediT roles: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualization; Roles/Writing - original draft; Writing - review & editing. Authorship statements should be formatted with the names of authors first and CRediT role(s) following. More details and an example.

Named Authors and Contributors

Every author must provide a signed Statement of Authorship form upon submission. This requirement applies to all article types including, but not limited to: editorials, sketches, letters, and replies.

Authorship requirements for submissions to the Journal must conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals from the International Committee of Medical Journal Editors. http://www.icmje.org and http://www.icmje.org/urm_full.pdf.

Each author named in the byline must qualify by having participated actively and sufficiently in the study reported. The basis for inclusion consists of 2 factors: 1) substantial contributions to (a) the concept and design or analysis and interpretation of data and (b) the author's having drafted the manuscript or revised it critically for important intellectual content; and 2) approval by each author of the version of the manuscript submitted. All conditions (1a, 1b, and 2) must be met. Others contributing substantively to the work, including participants in collaborative trials and persons involved solely in data collection, should be recognized separately in the Acknowledgment(s) section. The corresponding author must confirm that all bylined authors fulfilled all conditions described here.

Changes to authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.
Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.

Article transfer service

This journal is part of our Article Transfer Service. This means that if the Editor feels your article is more suitable in one of our other participating journals, then you may be asked to consider transferring the article to one of those. If you agree, your article will be transferred automatically on your behalf with no need to reformat. Please note that your article will be reviewed again by the new journal. More information.

AJOG Global Reports is a gold open access journal. Upon acceptance of an article, authors will be asked to complete an 'Exclusive License Agreement' (see more information on this). Permitted third party reuse of open access articles is determined by the author's choice of user license.

Author rights

Role of the funding source

You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.

Submission

Manuscript Submission Checklist

You are not required to submit the Manuscript Submission Checklist but must follow its instructions. The checklist distills many key parts of the Guide for Authors. Incomplete submissions will not be considered.

Statement of Authorship

Every author on ALL submissions must sign a Statement of Authorship.

Suggested Reviewers

Optional: Upon submission, authors may provide the names, institution, and email addresses of 2-3 potential reviewers for editorial consideration. Suggested reviewers may include anyone knowledgeable in the area of study presented. Reviewers should not be mentors or former colleagues, and ideally should not be in the same city as the author (unless there is no person with the needed expertise outside of this city).

Previous submission (unpublished)
Provide a copy of previous peer review comments and a detailed response to each point. This is required for any submission previously submitted to AJOG, optional if previously submitted elsewhere.

Translational Science

Translational science is typically presented in the form of an original research manuscript; however, the only type of non-clinical research considered must be translational in nature and contain biological implications for obstetrics and gynecology. Basic science without direct clinical relevance will not be considered; please see Editorial Policies for examples.

Requirements for the preparation of manuscripts

The author(s) accept(s) responsibility that the electronic file is complete and accurate upon submission, revision, and acceptance.

Editing Services

AJOG Global Reports publishes manuscripts only in American English. This includes using US spelling, punctuation, quotation marks, and decimal points. AJOG Global Reports editors strongly encourage contributors whose English is not excellent to have their manuscripts edited by a professional translator or native English speaker before submission. Elsevier offers authors two services to help prepare their manuscripts for submission to an English-language journal.

The first service edits your manuscript already written in English to ensure it is in correct scientific English. This process does not change the content of your manuscript but improves understanding and readability for an English-speaking reader. This process takes less than six business days and the cost of an average manuscript is less than $400. Please visit https://webshop.elsevier.com/language-editing-services/language-editing/pages/howdoesitwork.html for more details and to upload your manuscript. The second service translates your manuscript from your language (Chinese, Portuguese or Spanish) into either British or American English. This process is carried out by Language experts within your field, and takes less than 11 business days. The average cost is$1,000. Please visit https://webshop.elsevier.com/language-editing-services/language-editing/translationservices/pages/howdoesitwork.html for more details and to upload your manuscript.

Please note that these services are not mandatory for publication in an Elsevier journal. Using these services does not guarantee selection for peer review or acceptance, and you are not obligated to submit your edited manuscript to an Elsevier journal. Visit our customer support site.

Use of word processing software

It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier). Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

Basic Format

Requirements for manuscripts submitted to the Journal generally conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals from the International Committee of Medical Journal Editors (http://www.icmje.org).

Manuscripts must be submitted in American English, double spaced, with a font size no smaller than 12. Number pages consecutively in the upper right corner in the following order: title page, condensation and short version of title, abstract, main text, acknowledgments, references, tables, and figure legends.

IMPORTANT: Figures are to be uploaded individually and in separate files (one figure per file). DO NOT embed the figure into the manuscript text file, as this compromises the image quality, creating an unpublishable image (see artwork).

Use of Statistics and Math Formulae

In describing the statistical analyses performed, state which tests were used to evaluate a specific data set. In tables, indicate which statistical test(s) were used to evaluate the data.

Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, eg, X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

Abbreviations, Units, Proprietary (brand) Names, and Symbols

Use only standard abbreviations. Do not use abbreviations in the title or in the abstract. In the text they should be kept to a practical minimum. The full word or phrase for which an abbreviation stands should precede its first use in the text, with the abbreviation following in parentheses, unless it is a conventional standard unit of measurement.

The use of conventional units of measure is recommended, followed by Systeme International d'Unites (SI) units in parentheses. For this and other issues of style, authors are advised to consult the current AMA style manual: Iverson C, Christiansen S, Flanagin A, et al. AMA manual of style: a guide for authors and editors. 10th ed. New York, NY: Oxford University Press; 2007.

Generic, chemical, and/or proprietary names of drugs may be used. When a generic or chemical name is used, authors may insert the proprietary name in parentheses after the drug's first mention in the text (optional). When a proprietary drug name is used, it should be followed parenthetically (at first mention only) by the full name of the manufacturer and the city and state (US) or the city, province (if appropriate), and non-US country in which its main headquarters are located.Proprietary (brand names) are not permitted in the manuscript title.

Do not insert in any part of the paper the symbol for copyright (?), registered trademark (?), or trademark (TM); if included, they will be removed before publication.

Permissions

Direct quotations, tables, figures, and any other material that has previously appeared in copyrighted material must be accompanied by written permission for their use from the copyright owner and original author(s) along with complete reference information. Photographs of identifiable persons either must be accompanied by signed releases or all recognizable features must be masked.

Article structure

Essential Title Page Information

Title page (starting on page 1) - required for ALL article types, including: letters, replies, and online-only content - includes the following sequence:

1. Title (as concise as possible, approximately 12 words, without abbreviations or parenthetical abbreviations for terms used in the title, and suitable for indexing purposes) Proprietary (brand names) and conclusion statements are NOT permitted in the manuscript title
2. List of authors to be credited (byline), including each author's first name, middle initial, and LAST NAME (surname in all capital letters), with highest academic degrees (honorary degrees are not permitted); city or cities, state(s), province (Canada and Australia), and country or countries other than the United States in which the study was conducted; divisional and/or departmental and institutional affiliations of each author at the time the study was performed; for authors not called "Doctor," indicate Ms. or Mr.
Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
3. Disclosure statement of any potential of interest for each author; if no conflict exists; include the statement "The author(s) report(s) no conflict of interest."
4. Any source(s) of financial support for the research
Role of the funding source. You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement then this should be stated.
5. Required for clinical trials - include the clinical trial identification number and the URL of the registration site
6. Paper presentation information: if the findings were presented at a meeting, include the name of the meeting and its number (eg, "the 24th Annual Scientific Meeting" or "the 12th annual meeting"), the organization presenting the meeting, the city and state or city and non-US country (for Canada and Australia, include the province) in which the meeting was held, and the month, inclusive dates (not only the date on which the specific presentation was made), and year of the meeting
7. Disclaimer, if appropriate, such as for authors employed by the Federal Government or Armed Forces
8. The corresponding author's contact information (who will handle correspondence at all stages of submission, publication, and post-publication). Contact details must be kept up to date by the corresponding author. Include the full name, address, work and home and/or cell phone numbers (indicating which is which), fax number, and email address.

Word Count
The word count of the abstract and the main text (not counting the title page, condensation, acknowledgements, references, tables, figure legends, and figures) must be included at the bottom of the title page.

Text

The editors require that original research articles be organized into sections and identified with the following headings: (not applicable to review articles, clinical opinion, or other article types.)

The type(s) of non-human animals or other species used in an investigation must be named in the Title, Abstract, and Materials and Methods sections of the manuscript.

Introduction
State concisely the study's purpose and rationale. Present only the background, supported by a limited number of pertinent references necessary for the reader to understand why the study was conducted. Do not include study data or conclusions.

Materials and Methods
Describe briefly, but in sufficient detail to permit others to replicate the study, its plan, patients, experimental animals or other species, materials, and controls; methods and procedures; and statistical method(s) employed. Institutional Review Board (IRB) issues are to be addressed here as stated under "Human and nonhuman experimentation" in the Editorial Policies section above. If the study was exempt from IRB approval, provide an explanation in the Materials and Methods section of the paper.

Results
This section includes detailed findings and must cite, in numerical order, all tables and/or figures, which should supplement, not reiterate, the text. Emphasize only the most important observations. Reserve any comparisons with others' observations for the Comment section (see below).

Comment
Do not repeat the details of data presented under Results or present any new data here. The editors strongly advise the following structure:

• A brief statement of the principal findings, limiting claims to those strictly supported by the data, avoiding speculation and overgeneralization. Give equal emphasis to positive and negative findings of equal scientific merit.
• Strengths and weaknesses of the study, both intrinsically and in relation to other studies, particularly any differences in results.
• The meaning of the study; eg, hypothesized mechanisms that might explain the outcomes observed and/or the implications for clinicians or policy makers. Indicate whether additional research is required before the information can be confidently used in clinical settings.
• Unanswered questions; proposals for future research.

Acknowledgment(s)

This section thanks those other than the authors who have made substantive contributions to the manuscript, including participants in collaborative trials and persons providing only data collection or assistance with preparing the paper for submission or publication. Name only those who have made substantive contributions to the study (see "Editorial Policies").
For each person named under Acknowledgments, including science writers, the following information must be provided: name, place of employment, funding source(s), and disclosure of source of compensation, whether financial or in the form of services or complimentary products.
All individuals named in this section must consent to such acknowledgment.

References

Follow the format in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals from the International Committee of Medical Journal Editors. http://www.icmje.org Standard journal title abbreviations are available in the List of Serials Indexed for Online Users from the National Library of Medicine. http://www.nlm.nih.gov/tsd/serials/terms_cond.html

Numbering and order
All references are to be numbered sequentially as they fall in the text. For references that are not cited in the main text but only within table(s) or figure(s), begin such numbering after the numbers in the main reference list.

Insert citations in Arabic numerals as superscripts, not in parentheses. If the reference follows a comma or falls at the end of a sentence, the superscript should follow the comma or the period.

Do not include the first author of the cited reference in the text, in parentheses or otherwise, except as part of the text itself (Smith et al found?. or In a study by Smith et al, ....).

If any reference is repeated or out of order, the author is responsible for renumbering references as needed prior to submission or resubmission. If any reference(s) are added or deleted during editing, the author is responsible for renumbering all subsequent references, both in citations within the text (and tables and figures) and, correspondingly, in the reference list. For any citations used in tables or figure legends, renumbering should similarly be done there.

Reference style
In general references follow AMA style.

For up to 6 authors, list all; for 7 or more authors, list the first 3 + et al.

• Journal article
Nageotte MP, Vander Wal B. Achievement of the 30-minute standard in obstetrics-can it be done? Am J Obstet Gynecol 2012;206:104-7.
• Book chapter or section

If essential, these may be cited, within parentheses, at an appropriate location in the text, but not as numbered references. Written, signed permission from individual(s) quoted must accompany the manuscript upon submission.
For additional examples, see an recent issue of the Journal.

Abstracts
Abstracts of scientific meetings can be cited; however; once the complete work is published, the article citation is preferred.

Journal abbreviations source
Journal names should be abbreviated according to the List of Title Word Abbreviations: http://www.issn.org/services/online-services/access-to-the-ltwa/.

Provisional patent applications
Provisional patent applications may not be cited as a reference.

Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.

References in a special issue
Please ensure that the words 'this issue' are added to any references in the list (and add any citations in the text) to other articles in the same Special Issue.

Web references
Websites may or may not be appropriate sources for citation; e.g., websites that serve as repositories of genetic information maintained by NIH, NCI, and the National Library of Medicine are acceptable.

As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Tables

Submit tables in the manuscript file at the conclusion of the reference list and before the figure legends. Create all tables as double-spaced text in Microsoft Word. Any table submitted as a *.jpg or *.tif file will be returned for replacement.

Identify each table with a brief title (as few words as possible; reserve abbreviations for the key) and with an Arabic number (Table 1, Table, 2, etc.) in the order in which it is cited in the text. Each column, including the first, must have a heading. Put all explanatory matter in footnotes, including the spelling out of any nonstandard abbreviations used in the table.

For footnote symbols within tables, follow the style and order noted on pages 90-95 of the AMA style guide, 10th edition. For placement, start in the upper left corner and work across, left to right, and down, line by line.

If a table, in whole or in part, was derived from copyrighted material, a footnote at the bottom of the table must credit the original source, cited fully. Any copyrighted material must be accompanied by a letter or completed permission form at the time of manuscript submission.

Figure captions

Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Supplementary data

Elsevier accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at https://www.elsevier.com/artworkinstructions.

Appendices

If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

Figure legends

On the final page of the manuscript supply the following for each figure:
The figure number, figure title, and a 1- or 2-sentence description (legend, caption). Explain any arrowhead, letter, or other symbol used to identify parts of a photograph, drawing, or other illustration. Spell out any abbreviations used. In photomicrographs, explain the internal scale and identify the method of staining, if appropriate. If a figure was previously published by any of the bylined authors or others, insert a statement that permission has been granted and by whom, as well as a full citation of the original publication.

Figures

There is no charge for the use of color figures.
1. Submit each figure individually (one figure per file).
2. DO NOT copy and paste or embed images into the manuscript text file or in a slide presentation. This compromises image quality making it unpublishable.
3. Preferred image formats are: EPS, TIFF, or JPEG.
4. Number figures sequentially in order as they appear in the text, with Arabic numbers (Figure 1, Figure 2, Figure 3A, etc).
5. Assign to each figure a brief title (containing as few words as possible and reserving abbreviations for the legend).
For further explanation and examples of artwork preparation, see artwork instructions to authors at https://www.elsevier.com/artwork (click on "Artwork and Multimedia Instructions Interactive PDF").

Vidoes and Computer Graphics

Authors are encouraged to submit videos and computer-generated graphics; eg, a slide presentation with or without animation and sound. Although the publisher will not edit any video or computer graphic, the editors and reviewers may suggest changes. Any patient identification must be removed or masked. If music is utilized, appropriate permission is required.

Videos must be compatible with Windows Media Player and submitted in MPEG-1 or MPEG-2 (*.mpg) or QuickTime (*.mov) format. The maximum length of a video or computer graphic is 50 MBs or less per clip. Longer submissions may be divided into smaller clips, each of which should be identified at the beginning of that section; eg, Video Clip 1, Graphic 1. A concise legend for each video clip or computer graphic presentation must be included with the manuscript.

Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data.

For more detailed instructions please visit our video instruction pages at https://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

Videos and computer graphics accompanying a manuscript that is declined for publication will not be accepted separately. If the manuscript is accepted for publication, the presentation will be in the electronic version of your article, and in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com.

Illustration Services

Elsevier's WebShop (https://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Data references

This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. The [dataset] identifier will not appear in your published article.

Reference management software

Most Elsevier journals have their reference template available in many of the most popular reference management software products. These include all products that support Citation Style Language styles, such as Mendeley. Using citation plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal's style. If no template is yet available for this journal, please follow the format of the sample references and citations as shown in this Guide. If you use reference management software, please ensure that you remove all field codes before submitting the electronic manuscript. More information on how to remove field codes from different reference management software.

Data Visualization

Include interactive data visualizations in your publication and let your readers interact and engage more closely with your research. Follow the instructions here to find out about available data visualization options and how to include them with your article.

Research data

This journal encourages and enables you to share data that supports your research publication where appropriate, and enables you to interlink the data with your published articles. Research data refers to the results of observations or experimentation that validate research findings. To facilitate reproducibility and data reuse, this journal also encourages you to share your software, code, models, algorithms, protocols, methods and other useful materials related to the project.

Below are a number of ways in which you can associate data with your article or make a statement about the availability of your data when submitting your manuscript. If you are sharing data in one of these ways, you are encouraged to cite the data in your manuscript and reference list. Please refer to the "References" section for more information about data citation. For more information on depositing, sharing and using research data and other relevant research materials, visit the research data page.

If you have made your research data available in a data repository, you can link your article directly to the dataset. Elsevier collaborates with a number of repositories to link articles on ScienceDirect with relevant repositories, giving readers access to underlying data that gives them a better understanding of the research described.

For supported data repositories a repository banner will automatically appear next to your published article on ScienceDirect.

In addition, you can link to relevant data or entities through identifiers within the text of your manuscript, using the following format: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).

Mendeley Data

This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols, and methods) associated with your manuscript in a free-to-use, open access repository. During the submission process, after uploading your manuscript, you will have the opportunity to upload your relevant datasets directly to Mendeley Data. The datasets will be listed and directly accessible to readers next to your published article online.

Data statement

To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.

Review and Publication Process

Each manuscript submission will be acknowledged in the order received in the Editorial Office. The acknowledgment letter will note the number assigned to the manuscript. All subsequent inquiries about the manuscript must indicate the manuscript number. Usually two and sometimes several reviewers and Editorial Board members will participate in the review of a manuscript. The journal does not reveal the identity of its reviewers but does provide pertinent comments to the corresponding author. Re-review may be required after revision if, in the judgment of the Editor-in-Chief, sufficient modification of the manuscript or data justifies another review cycle or if one (or more) of the reviewers requested to see the revision. The Editor-in-Chief has final authority on all editorial decisions unless the editor has been recused, e.g., if the editor is an author, in which case the review process is overseen and the decision made by a designated Associate Editor. Appeals Regarding Manuscripts Rejected by AJOG Global Reports The Journal is able to accept a relatively small percentage of submissions received. Therefore, many good manuscripts are declined, oftentimes despite favorable peer reviews. If your paper is rejected but the reviews are accurate, please do not appeal the decision and request additional reviews. Doing so distracts the journal's editors and reviewers from evaluating submissions and editorial staff from processing other manuscripts and is unfair to the authors of those papers. If, however, the reviewer or editor assessments are reconsidered, the Editor-in-Chief will entertain an appeal and reopen the manuscript's file. Any appeal must be made by the corresponding author to the Editorial Office by email prior to resubmitting the manuscript. Please do not resubmit a revised version of a rejected manuscript without an appeal to the Editorial office. Please do not resubmit until your original manuscript is released back to you. By waiting for the manuscript release, it ensures that your paper is processed under the same manuscript number, keeping the manuscript history intact.

Peer Review

This journal operates a single-blind review process. All contributions will be initially assessed by an editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor-in-Chief is responsible for the final decision regarding acceptance or rejection of articles. The Editor-in-Chief's decision is final. AJOG Global Reports Editors have active research programs and on occasion publish work in the Journal. Editor/authors are masked to the peer review process and editorial decision-making of their own work and are not able to access this work in the online manuscript submission system. Work by Editor/authors is assessed using the same criteria as that applied to all AJOG Global Reports submissions.

Proofs

One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or a link will be provided in the e-mail so that authors can download the files themselves. To ensure a fast publication process of the article, we kindly ask authors to provide us with their proof corrections within two days. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download the free Adobe Reader, version 9 (or higher). Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and scan the pages and return via e-mail. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.

Offprints

The corresponding author will be notified and receive a link to the published version of the open access article on ScienceDirect. This link is in the form of an article DOI link which can be shared via email and social networks. For an extra charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. Both corresponding and co-authors may order offprints at any time via Elsevier's Author Services.

Use of the Digital Object Identifier

The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B): http://dx.doi.org/10.1016/j.physletb.2010.09.059

When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.
