The first step in submitting an article is to determine the type of article. This is because the type of article determines the rules that must be followed, including the format and word limit of the article. The main categories of article types and the guidelines for preparing them are summarized below:

Orginal Articles:

These are original articles containing new research. These articles may include randomized controlled trials, observational (cohort, case-control, or cross-sectional) studies, descriptive studies, diagnostic accuracy studies, systematic reviews and meta-analyses, non-randomized behavioral and public health intervention studies, experimental animal studies, or other clinical or experimental studies. The original research should report scientifically sound experiments and provide substantial new information. The article should include the most recent and relevant references in the field. The structure should include an Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion, and Conclusions sections. Abstracts should not exceed 500 words and should include the following subheadings: Background, Objectives, Study Design, Methods, Results, and Conclusions. The main text should include the following subheadings: Introduction, Materials and Methods, Results, Discussion, Conclusions, Acknowledgments, References, Tables, and Figure Legends. The main text, excluding the abstract, references, tables, and figure legends, should not exceed 3,000 words. There should be a maximum of 50 references. All papers but cell studies require ethical approval. The final length and format will be determined by the editorial staff during the review process or when the accepted manuscript is edited.

Review Articles:

Reviews should be comprehensive articles describing the latest developments in any field of medicine and health science. Reviews comprehensively analyze the current literature in a field of study, identify existing gaps or problems. They should be critical and constructive and offer suggestions for future research. New, unpublished data should not be presented. The structure can include an Abstract, Keywords, Introduction, Relevant Sections, Discussion, Conclusions, and Future Directions. The main text of a review article should not exceed 5,000 words (excluding references, tables, and figure captions), and the abstract should not exceed 500 words. A review article may be authored by up to 7 authors and may include up to 100 references.

Case Reports:

Case reports and series should address unexpected or new findings, such as side effects, medication interactions, disease presentations, and courses, and/or manifestations of illness that suggest a new scientific understanding. They should have value for medical knowledge and raise questions about current diagnosis and treatment, sometimes suggesting change in practice may be necessary. For the Case Report article type, the manuscript should be limited to the presentation of 1-3 cases. If the manuscript presents ≥ 4 cases (e.g., a case series), then please submit the manuscript under the Original Research article type.The case(s) should include relevant history, physical and laboratory findings. The report should include a review of prior cases and case series. The manuscript should include an abstract, followed by a brief background and context, the case(s), and a discussion, that in addition to reviewing prior cases, should make clear what the new knowledge is and its implications. The text cannot exceed 2000 words, no more than one table, no more than one figure or image, and up to 30 references. Word count includes only the main body of text (i.e., not tables, figures or references).  Case reports must address the issue of consent in accordance with the Journal policy.

Brief Reports:

A brief report describing exciting findings in a particular field of medical science with high quality and broad interest can be submitted. The short communication should be brief yet concise, and no specific subsections are required. These submissions should consist of scientifically rigorous research that can be reported in a shorter format because the work is preliminary, or because the findings are focused, with one major conclusion. The main text should be less than 2000 words with a maximum of 30 references and have no more than three display items (Tables or figures). Abstracts should not exceed 300 words and should be structured with the following subheadings: Aims, Methods, Results, and Conclusion. All papers require ethical approval.

Letters to the Editor:

Letters can be responses to articles in the journal, replies to other letters, or standalone communications about issues of importance in academic medicine. They must not duplicate other material that has been published or submitted for publication. The text cannot exceed 500 words, no more than one table or figure, and up to 10 references. Word count includes only the main body of text (i.e., not tables, figures or references). They have no more than four authors. Submissions do not require an abstract. The cover letter that accompanies submissions must include the full citation of the article or letter being commented upon. Letters and replies will be published at the discretion of the editor and are subject to abridgement and editing for style and content. Authors might be asked for a reply to the letter. Replies must be submitted through submission system as well.

Editorials:

Editorial comments are a brief remark on an article published in the journal by the reviewer of the article or by a relevant authority. Most comments are invited by the Editor-in-Chief but spontaneous comments are welcome. It must not exceed 1000 words (excluding references). An abstract is not required with this type of manuscripts. It can have no more than 15 references and 1 figure or table.
