Author Guidelines

Scope and Types of Manuscripts The Indonesian Journal of Obstetrics and Gynecology (INAJOG) welcomes submissions in the form of original research articles and case reports from scholars and practitioners in the field. Manuscripts must be original, not previously published or under consideration elsewhere, and should be written in English. The length of each submission should not exceed 5,000 words or ten pages. Titles are expected to be concise, specific, and informative, accompanied by a short running title of no more than fifteen words. Authors must provide their full names, the corresponding author’s address for proofs, and the institutional affiliation to which the work should be attributed.

Abstract and Keywords Each manuscript must include an abstract of no more than 250 words, summarizing the background, objectives, methods, results, and conclusions of the study. The abstract should be followed by three to five keywords that reflect the core content of the work.

Introduction The introduction should present the background of the problem, articulate the research question, and state the objectives of the study. It must provide sufficient context to justify the relevance and importance of the research.

Methods The methods section must describe the materials and procedures in sufficient detail to allow replication. Established methods should be properly referenced, while new or modified methods must be explained thoroughly. Ethical approval must be clearly stated for all studies involving human subjects.

Results Results should be presented in a logical sequence, supported by tables and figures only when necessary to highlight key findings. Decimal numbers must use a point as the separator. Tables, figures, and photographs should be cited consecutively in the text, and non‑standard abbreviations must be defined at their first mention. Mathematical equations should be clearly stated.

Discussion and Conclusion The discussion should interpret the results, explain their significance, and compare them with previous studies. Authors are expected to highlight how their findings contribute to solving the research problem, acknowledge limitations, and suggest directions for future research. This section should conclude with a clear statement of the study’s overall findings. The conclusion itself must provide concise answers to the research question in clear and descriptive sentences.

References References must follow the Vancouver style and be managed using applications such as Mendeley or EndNote. Authors are required to include at least two citations from INAJOG. References must be cited in the text using superscript Arabic numerals, numbered consecutively in order of appearance, and listed at the end of the manuscript in numeric sequence.

Structure of Articles Research articles should be organized into title, author information, abstract, objectives, methods, results ending with a conclusion, and references. Case reports or case series should be structured into title, author information, abstract, introduction, case description and management supported by photographs or illustrations, discussion ending with a conclusion, and references.

Tables and Figures Each article may contain a maximum of three tables, figures or graphs. Photographs, whether in color or black and white, must be clear and of high quality. All tables and figures must be numbered consecutively and cited in the text.

Formatting Requirements Manuscripts must be submitted through the INAJOG website, typed with 1.5 line spacing on A4 paper, in single‑column format, with margins of 2.5 cm on all sides.

Authorship (ICMJE Standards) In accordance with the recommendations of the International Committee of Medical Journal Editors (ICMJE), authorship must be based on four essential criteria. Each author should have made a substantial contribution to the conception or design of the work, or to the acquisition, analysis, or interpretation of data. They must have participated in drafting the manuscript or revising it critically for important intellectual content, approved the final version to be published, and agreed to be accountable for all aspects of the work, ensuring that questions related to accuracy or integrity are appropriately investigated and resolved. Contributors who do not meet all of these criteria should be acknowledged separately.

Publication Ethics (COPE Principles) In line with the principles of the Committee on Publication Ethics (COPE), all authors are required to disclose any potential conflicts of interest that may influence the interpretation of their work. The journal strictly prohibits plagiarism, data fabrication, falsification, and duplicate publication. Editors are committed to ensuring a fair and confidential peer review process, while reviewers are expected to provide objective assessments and declare any conflicts of interest. Should serious errors or ethical concerns be identified after publication, the journal will issue corrections or retractions following COPE’s established flowcharts and procedures.
