General Principles

As a basic requirement, all articles submitted to the Medical Journal of Indonesia must be original work, which has never been published previously and is submitted exclusively to the Medical Journal of Indonesia. They must be written in the format of “Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals” (, which was established by the International Committee of Medical Journal Editors (ICMJE) and updated in December 2018. The Editorial Board reserves the right to edit all articles in aspects of style, format, and clarity. Authors may be required to revise their manuscripts for reasons of any aspect. Manuscripts with excessive errors in any aspect may be returned to authors for retyping or may be rejected. All manuscripts will be subjected to peer and editorial review.

We accept types of articles: (1) original articles: basic medical research, clinical research, or community research; (2) case report; (3) review article; (4) brief communication; (5) correspondence.

Authors must also supply:

  1. ICMJE conflicts of interest statement form (if there are any difficulties in accessing the form, you can directly visit here,
  2. copy of ethical approval (for all type of researches involving human and animal), and
  3. final checklist signed by all author(s).

A cover letter should be provided along with the submission addressed to the Editor-in-chief of Medical Journal of Indonesia which should include a statement about all previous submissions of the manuscript and previous reports that might be regarded as redundant publication of the work. If the manuscript has been submitted previously to another journal, authors are encouraged to provide previous comments along with the responses to accelerate the review process. Author(s) also have to mention the work whether it has been presented in a congress/conference/seminar.

Templates are available for original articles and case reports.

All articles must be conformed with international standard guidelines which can be found in, for example: randomized controlled trial – CONSORT, observational studies – STROBE, systematic review and meta-analysis – PRISMA, case report – CARE, and so on.


Study Ethics

All submitted papers containing animal experiments and/or involving human subjects should have obtained approval from an independent ethics committee. The copy of approval should be provided to the editorial office as mentioned above.


Publication Ethics

The publisher of this journal is a member of Committee on Publication Ethics (COPE). This journal follows guidelines from COPE in facing all aspects of publication ethics and, in particular, how to handle cases of research and publication misconduct. All articles in this journal involving human subjects should respect principles of research ethics as described in the Declaration of Helsinki and studies involving animals should obey the International Guiding Principles for Biomedical Research as developed by the Council for International Organization of Medical Sciences (CIOMS).

Medical Journal of Indonesia adapts COPE principle to meet high quality standard of ethics for publisher, editors, authors, and reviewers. As an essential issue, publication ethics need to be explained clearly to improve the quality of research worldwide. In this part, we explain the standard for editors, authors, and reviewers. In addition, publisher does not have the right to interfere with the integrity of the contents and only support to publish in timely manner.


Clinical Trial Registration

The authors are encouraged to register all clinical trials to the publicly accessible registration in any registry as recommended by ICMJE or integrated to WHO International Clinical Trials Registry Platform (ICTRP) or in, which is a data provider to the WHO ICTRP. The trial registration number should be provided at the end of the abstract. The registration should be done prior to the conduct of the trial.


Structure and Language

Articles will be published in US English, following American spelling. Articles in English that are linguistically inadequate may be rejected. Manuscripts should be written double-spaced in all parts of the manuscript using Times New Roman 12, with margin of 2.54 cm of all sides. Articles must be submitted in the following structural order: title page and authorship, abstract, keywords, text, conflicts of interest, acknowledgments (if any), funding sources, references, tables, figures, and legends (if any).


Title Page and Authorship

The Title Page should contain: title of the article (concise, no abbreviations, maximum 16 words); full names of authors (without academic titles); authors’ affiliations [name(s) of department(s) and institution(s)]; disclaimers (if any); corresponding author’s name, mailing address, telephone and fax numbers, and e-mail address (institution specific address and e-mail address of the corresponding author will be published along with the article); source(s) of support in the form of grants, equipment, drugs, or all of these (if any); short running title [maximum 40 characters (letters and spaces)]; word counts [A word count for the text only (excluding abstract, acknowledgments, tables, figure legends, and references)]; number of figures and tables; and conflict of interest declaration for each author.

Authorship of articles should be limited to those who have contributed sufficiently to take public responsibility for the contents. This includes (a) conception and design, or analysis and interpretation of data, or both; (b) drafting the article or revising it critically for important intellectual content; (c) final approval of the version to be published; (d) and agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Contributors who meet fewer than all four criteria above should be listed in acknowledgments and the contributions should be specified. Corresponding authors should assure the permission of acknowledged individuals to be mentioned in the acknowledgment.


Abstract and Keywords

The abstract should be formally structured and prepared in English with a maximum of 250 words for biomedical, clinical, and community research articles and systematic review or meta analysis; for case reports, brief communications, and narrative reviews, the abstract should not be structured formally and should not exceed a maximum of 150 words. Abstracts should be concise and precise with enough information, highlighting the points and importance of the article. It should contain: background and purpose of the study; methods (basic procedures, study subject selection, observational or analytical methods); main findings or results; and principal conclusion. Keywords are limited to 3 - 6 words or short phrases that will allow proper and convenient indexing. They should be obtained from Medical Subject Headings (MeSH®) thesaurus produced by National Library of Medicine.


Main Text

The main text should be structured as introduction, methods, results, and discussion (IMRAD). Methods should provide clarity about how, why, and when the study was done. The methods section should include the statement of approval by local, regional, or national review board. It should also clearly describe the selection of the study’s participants. Materials and equipment used should be identified in methods section by specifically giving the manufacturer’s name and address in parentheses. References to all established methods must be given. All statistical methods used should be described in detail in the methods section of the manuscript. Relying solely on statistical hypothesis testing, such as p values should be avoided; instead, important information about effect size and precision of estimates should be provided. Statistical terms, abbreviations, and symbols should be defined and computer software and version used should be specified. In the results section, data should be presented in a concise and precise way, either in figures or tables, but not the same finding in a figure and a table. Unnecessary figures and tables, as well as footnotes should be avoided and their contents incorporated into the text. In the last sentence of the discussion a conclusion should be stated.



Use only standard abbreviations; use of nonstandard abbreviations can be confusing to readers. Avoid abbreviations in the title of the manuscript. When first mentioned, all abbreviations must be spelled out followed by the abbreviation in parenthesis, unless the abbreviation is a standard unit of measurement. Abbreviations must be spelled out when first mentioned in the abstract and main text. If a sentence begins with a number, it should be spelled out except in abstract.


Conflicts of Interest

Conflicts of interest should be transparent as detail as possible as provided in the ICMJE form as a standardized authors’ disclosures. Financial and personal relationships are easily identifiable that might bias or be seen to bias the work. Funding sources for the work should be described specifically with explanations of the role of those sources and the authors should declare that the supporting sources had no involvement in specific role. The authors should declare that the authors had access to all the study and the sponsors did not intervene the data or the work. Each author should submit a separate form from ICMJE.



Personal acknowledgments should be limited to appropriate proffesionals who contributed to the paper, including technical help and financial or material support, also general support by a department chairperson.


Funding Sources

Funding sources for the work should be described specifically with explanations of the role of those sources and the authors should declare that the supporting sources had no involvement into nor influence on the content of the manuscript. This statement should be written separately and limited to the funding for the work. If funder(s) had any impact into or influence on the design; data collection, management, analysis and interpretation of the data, the preparation, review, or approval of the manuscript or the decision to submit the manuscript for publication, their role must be disclosed in detail.


Tables and Figures

Total number of tables and figures are advisable not to exceed 6 in number. Tables and its title should be presented in separate sheets. Tables should be numbered in Arabic numerals, captions should be brief, clearly indicating the purpose or content of each table. Provide a footnote to each table, identifying in alphabetical order all abbreviations used. Number tables consecutively in the order of their first citation in the text and supply a brief title for each. Do not use internal horizontal or vertical lines. Give each column a short or an abbreviated heading. Explain all nonstandard abbreviations and explanatory matters in footnotes, and for explanatory matters use the following symbols, in sequence: *, †, ‡, §, ¶, **, ††, ‡‡, §§, ¶¶, etc. Identify statistical measures of variations, such as standard deviation and standard error of the mean. Be sure that each table is cited in the text. If you use data from another published source, obtain permission and acknowledge that source fully.

Figures should be either professionally drawn or photographed, and submitted in a format (JPEG or TIFF) in the following resolutions [gray-scale or color in RGB (red, green, blue mode) at least 300 dpi (dots per inch). For x-ray films, scans, and other diagnostic images, as well as pictures of pathology specimens or photomicrographs, send sharp, glossy, black-and-white or color photographic prints, usually 127 x 173 mm (5 x 7 inches). Write the word “top” on the back of each figure at the appropriate place. Figures should be made as self-explanatory as possible, titles and detailed explanations belong in the legends-not on the figures themselves. Photomicrographs should have internal scale markers. Symbols, arrows, or letters used in photomicrographs should contrast with the background. When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one clearly in the legend. Explain the internal scale and identify the method of staining in photomicrographs. Photographs of potentially identifiable people must be accompanied by written permission to use the photograph.

Tables and figures should be numbered consecutively according to the order in which they have been cited in the text. If a table or figure has been published previously, acknowledge the original source and submit written permission from the copyright holder to reproduce it. Permission is required irrespective of authorship or publisher except for documents in the public domain using license of CC BY SA. Color figures are allowed in special circumstances, provided that the author is willing to cover the cost of reproduction. If the original size of the figures is too large, you can provide us lower quality figures on submission and ensure the availability of good quality figures after the acceptance of the manuscript.


Units of Measurement

For measurements use both local and S.I. (System International) units. Measurement units should be abbreviated (e.g. mm, kcal, etc.) in accordance with the Style Manual for Biological Sciences and using the metric system. Measurements of length, height, weight, and volume should be reported in appropriate scientific units. Temperatures should be in degrees Celsius. Blood pressures should be in millimeters of mercury (mmHg). Drug concentrations may be reported in either SI or mass units, but the alternative should be provided in parentheses where appropriate.



Use Arabic numerals in supercript to cite references in National of Medicine style. References are advisably not to exceed 25 in number but not less than 10, and should in general be limited to the last decade, except for references to methods used: they must be cited no matter how old they are. More than 25 references may be accepted when it is necessary. References must be numbered in the order in which they are mentioned in the text. Use the style of the examples below, which are based on the International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals: Sample References. The titles of journals should be abbreviated according to the style used for MEDLINE. Avoid using abstracts as references. Information from manuscripts submitted but not yet accepted should be cited in the text as “unpublished observations” with written permission from the source. Papers accepted but not yet published may be included as references; designate the journal and add “Forthcoming”. Avoid citing “personal communication” unless it provides essential information not available publicly, name the person and date of communication, obtain written permission and confirmation of accuracy from the source of personal communication. Authors are recommended to use reference management software, in writing the citations and references such as: Mendeley®, Zotero®, EndNote®, and Reference Manager®.
