Evidence-Based Medicine
For the specific study design, such as randomized control studies, studies of diagnostic accuracy, meta-analyses, observational studies and non-randomized studies, it is recommended that the authors follow the reporting guidelines listed in the following table.
Initiative Type of study Source
CONSORT Randomized controlled trials http://www.consort-statement.org
STARD Studies of diagnostic accuracy http://www.stard-statement.org
PRISMA Preferred reporting items of systematic reviews and meta-analyses http://www.prisma-statement.org
STROBE Observational studies in epidemiology http://www.strobe-statement.org
MOOSE Meta-analyses of observational studies in epidemiology http://www.consort-statement.org/resources/downloads/otherinstruments/moose-statement-2000pdf
Registration of Clinical Trial Research
Any research that deals with a clinical trial is recommended to be registered with a primary national clinical trial registration site such as http://ncrc.cdc.go.kr/cris, or other sites accredited by WHO or the International Committee of Medical Journal Editors.
Copyright and Permission
All published papers become the permanent property of the Korean Society of Obstetrics and Gynecology. A copyright transfer form should be submitted to the editorial office by fax, regular mail or e-mail on acceptance.
If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, illustrations, and tables.

Manuscripts Submission
Manuscripts should be submitted on-line at (http://submit.ogscience.org). Submission instructions are available at the website. All articles submitted to the journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication.
Peer Review Process
The editor selects peer referees by recommendation of the Editorial Board members or from the specialist database owned by the Editorial Board. Acceptance of the manuscript is decided, based on the quality and originality of the research and its clinical and scientific significance by the referees. A referee’s decision is made as “acceptance without revision,” “acceptance after minor revision,” “review after revision” and “rejection.” If there is marked discrepancy in the decisions between two referees or in opinions between the author and referee(s), the Editor may send the manuscript to another referee for additional comments and recommended decision. Three repeated decisions of “review after revision” are regarded as “rejection.” An initial decision will normally be made within 4 weeks of receipt of a manuscript, and the reviewers’ comments are sent to the corresponding authors by e-mail. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the referees’ comments item by item. Failure to resubmit the revised manuscript within 8 weeks of the editorial decision is regarded as a withdrawal.

General Guideline
After entering all the checklist and information about authors, manuscript title, abstract, keywords and other details, you will be prompted for uploading fi les. The main document with manuscript text and tables should be prepared with an MS-word.

  • The main document should be organized in the following order: title page, abstract and keywords, introduction, materials and methods, results, discussion, acknowledgments, references, tables, figures and figure legends.
  • The manuscript should be written in 10-point font with double spacing on A4 sized (21.0×29.7 cm) paper with 2.5 cm margins on the top, bottom, right, and left.
  • All manuscript pages are to be numbered at the middle of bottom consecutively, beginning with the title page as page 1.
  • The use of acronyms and abbreviations is discouraged and should be kept to a minimum. Acronyms and abbreviations cannot be used in the title. When used, they are to be defined where first used, followed by the acronym or abbreviation in parentheses.
  • Drug and chemical names should be stated in standard chemical or generic nomenclature. Units of measure should be presented according to the International System (SI) of units.
  • 1) Title page
    Include the following items on the title page: the title of the article, the full names and institutional affiliations of all authors. A short running head must also be provided, consisting of fewer than 40 characters including spaces. When other authors with a different address are included, first write the name of the organization where the primary research was conducted and the names of the other organizations along with the authors’ names, listed in numerical order. At the bottom of the title page, write the corresponding author’s address, phone, fax, and e-mail address.
    2) Abstract and Keywords
    The abstract should be no more than 250 words, and describe concisely, in a paragraph, Objective, Methods, Results, and Conclusion. Up to 5 alphabetized keywords should be listed at the bottom of abstract to be used as index terms. For the selection of keywords, refer Medical Subject Heading (MeSH, http://www.ncbi. nlm.nih.gov/mesh) in Medline.
    3) Introduction
    Briefly describe the purpose of the investigation, including relevant background information.
    4) Materials and Methods
    Describe the research plan, the materials (or subjects), and the methods used, in that order. Explain in detail how the disease was confirmed and how subjectivity in observations was controlled. When experimental methodology is the main issue of the paper, describe the process in detail so as to recreate the experiment as closely as possible. The sources of the apparatus or reagents used should be given along with the source location (name of company, city, (state), and country). Information on the institutional review board/ethics committee approval or waiver and informed consent should be stated. Methods of statistical analysis and criteria for statistical significance should be described.
    5) Results
    The results should be presented in logical sequence in the text, tables, and illustrations. Do not repeat in the text all data in the tables or figures, but describe important points and trends.
    6) Discussion
    Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents in the introduction or results. Explain the meaning of the observed opinion along with its limits, and within the limits of the research results connect the conclusion to the purpose of the research.
    7) Acknowledgments
    If necessary, persons who have made substantial contributions, but who have not met the criteria for authorship, are acknowledged here. All sources of funding applicable to the study, disclosure of potential conflicts of interest including financial interests, activities, relationships and affiliations, information on previous presentation and any important disclaimers should be stated here explicitly.
