Instructions for Authors
GMJ Medicine publishes diverse categories of articles. All types of articles are subject to peer-review. The journal publishes the following types of contribution:
GMJ Medicine Article Types:
Editorials are the message of the GMJ Medicine and are written in-house by the journal's Editorial Board members. Editorials are preferably no more than 3000 words. An unstructured abstract is required for these types of articles.
These articles consist of Systematic Review, Meta-analysis, Systematic Reviews and Meta-analysis, Meta-Synthesis, Scoping Review, Literature Review, and Narrative Review. These articles may be up to 7000 words excluding abstract, tables, and references. Inclusion and exclusion criteria for studies should be described in a flow diagram. The specific type of study or analysis, intervention, population, exposure, outcomes or tests should be described for each data source or article. Authors are to clearly cover the following topics in the method section: search strategy and selection criteria, data extraction, quality assessment, and data analysis. A structured abstract is required that should include: Background; Methods and Analysis; Discussion; Registry and number (if the protocol of these articles had been registered in a registry system). For these articles authors need to complete and include a PRISMA-P checklist (please find it from here) and upload as a supplementary file. Authors must ensure that all points are included and state page numbers where each item can be found.
These articles must be of primary research, methodologically accurate, and relevant to GMJ Medicine. They should contain no more than 7000 words excluding structured abstract, tables, and references. Each manuscript should clearly state an objective or hypothesis; the design of study and methodology (including study setting, patients or participants, inclusion and exclusion criteria, sampling and data source); data analysis and interpretations; the main results of the study, discussing the results; addressing study limitations and the conclusion. For all original articles, a structured abstract is required. All original articles are required to have Key Messages as research highlights that provided in one paragraph in title page. Only original articles require Key Messages.
communications are short articles (mini original articles) that present original and important preliminary findings that do not warrant publication as a full-length article but are still worthy of publication. Short communications should have an un-structured abstract and should not be more than 4000 words including references and up to three tables or figures. The main text should be sub-divided into background, methods, results, and discussion, but should be written as concisely as possible. To maintain brevity, these articles do not need key messages.
Letter to Editor
We welcome short letters with topics of interest to the GMJ Medicine readership. These letters should not exceed 1000 words including only one table or figure, references and the main text. No abstract is required for these articles.
Please insert the type of your manuscript on top of the Title Page and Main Manuscript.
Ethics in Publishing
As GMJ Medicine follows the guidelines of Committee on Publication Ethics (COPE), for information on this matter in publishing and ethical guidelines please visit COPE.
Please note that any submission that has data collected from human subjects requires ethics approval. In this case, a clear statement to this effect must be made in any submitted manuscript presenting such research, specifying that the free and informed consent of the subjects was obtained. If your manuscript does not include ethics approval, your article will not be sent out for review. For qualitative articles it is mandatory that the following general principles be considered when submitting your manuscript.
Details of formal ethical approval should be stated in the main body of the article. If authors were not required to obtain ethical approval (as is the case in some countries) or unable to obtain attain ethical approval (as sometimes occurs in resource-poor settings) they should explain this. Please anonymize this information as appropriate in the manuscript, and give the information when asked during submission.
Procedures for securing informed consent should be provided.
- Responsibilities of authors:
Permission to use or publish an institution data: If you wish to publish the data/information of an institution, you should seek the institution permission and provide us with the signed permission once we ask for this. During submission you should inform us if you have obtained such permission.
Using Website information: Most materials on the Internet are protected by copyright. In such case you need to obtain permission from the website which owns the copyright. Some website materials, however, may not be original to the website and you need to identify the right-holder and seek permission.
- Informed consent
According to ICMJE guidelines patients or, in general research, participants have a right to privacy that should not be infringed without informed consent. Identifying information, including patients' names, initials, or hospital numbers, should not be published in written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that a patient who is identifiable be shown the manuscript to be published. Authors should identify individuals who provide writing assistance and disclose the funding source for this assistance.
- Conflict of interest
According to ICMJE guidelines, a conflict of interest may exist when an author (or the author’s institution), reviewer or editor has personal or financial relationships that influence (bias) inappropriately his/her action (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships vary from those with negligible potential to those with great potential to influence judgment, and not all relationships represent true conflict of interest. The potential for conflict of interest can exist whether or not an individual believes that the relationship affects his or her scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, and of science itself. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion. Authors must make sure that they have declared any actual or potential conflicts of interest in their manuscript when submitting their work (if any). The corresponding author is responsible for confirming with the co-authors whether they have any conflicts to be declared or not (For further information please visit ICMJE).
GMJ Medicine uses the Crosscheck iThenticate Plagiarism detector to screen submitted manuscripts for originality. Using this service, we can detect if a manuscript contains passages of text that appear in other publications or resources. Crosscheck is an initiative between iThenticate and CrossRef®, a not-for-profit membership association of publishers, established to help publishers prevent professional plagiarism and other forms of scholarly misconduct. With thousands of journals sharing published works with the iThenticate database, the CrossCheck service offers publishers a way to compare documents against the largest comparison database of scientific, technical and medical content in the world.

Main Manuscript Components
The manuscript should follow through these sections: Abstract (no more than 350 words), Key Messages (only for Original Articles), Background, Methods, Results, Discussion, Conclusion, and References. However, it may be appropriate to combine the discussion and conclusion sections in some articles. Tables and Figures should be inserted within the text as close as possible to where they are referenced. Authors should not upload them as separate files. Please add page numbers and line numbers for your manuscript.
Include a structured abstract of no more than 350 words for original articles and reviews. An abstract is often presented separately from the article, so it must be able to stand alone. It should state briefly and clearly the purpose and setting of the research, the principal findings and major conclusions, and the article's contribution to knowledge. Abstracts should be prepared in GMJ style including background, methods, results and conclusion. For other manuscripts, include an unstructured manuscript of no more than 300 words that summarizes the objectives and background, main points and conclusions of the article. Abstracts are not required for correspondence, and letters to editors.
Authors need to add up to 5 keywords separately into the online system during submission, and should accurately reflect the content of the article. Abbreviations/acronyms could be used with their expansions. The keywords will be used for indexing purposes. Please prepare the keywords according to the following instructions:
3-5 Keywords (single or phrases with no more than 3 words)
Contain words and phrases that suggest what the topic is about
Use variants terms or phrases that readers are likely to use
If the article focuses on a particular region (geographic, climatic, etc.), use that as a keyword
Use specific phenomena or issues as keywords (climate change, air pollution, etc.)
Should be prepared left to right and cell-based (i.e., created in Word with the Tables tool).
Table number and caption always appear above the table. Leave 2 line spaces between the table and the caption.
Should be editable and upright on the page, not on sideways.
Should be prepared with real rows and columns and not aligned with tabs, returns, or spaces.
Multi-part tables with varying numbers of columns or multiple footnotes should be organized as separate tables.
Should be plain with NO colors, shading, or graphics.
Should not contain inserted text boxes, tables within tables or cells within cells.
Should be cited in numerical order upon their first mention.
Symbols and abbreviations should be defined immediately below the table, followed by essential brief description.
All tables should be inserted within the text as close as possible to where they are referenced. Authors should not upload them as separate files.
All figures/images must be cited within the main text in numerical order.
All figures/images must be centered. Figure number and legend always appear below the figure. Leave 2 line spaces between the figure and the legend.
Figures must be prepared in one of the following formats: Adobe Portable Document Format (PDF) for photography or microscopy, Encapsulated PostScript (EPS) for illustrations or diagrams, Tagged Image File Format (TIFF), EPS, or PS. Files prepared with Adobe Illustrator, Corel Draw or Adobe Photoshop should be uploaded in these native file formats.
All digitized images must be of high quality; that is, resolutions of at least 300 dpi for color figures, 600 dpi for greyscales and 1200 dpi for line arts.
Histograms should be prepared in a simple, two-dimensional format, with no background grid.
Make sure that any specific patient/hospital details are removed or blacked out (e.g., X-rays, MRI scans, etc).
If photographs of patients are used, they should not be identifiable. However, do not use a black bar to obscure a patient’s identity.
Original data from which the images were prepared should be available, as the editors may request to see these data (e.g., Office, SPSS and other line art images).
Lettering in figures (e.g., labeling of axes) should be in lower-case type, with the first letter capitalized and no full stop. All text should be in a sans-serif typeface, preferably Arial with size 8 pt.
Avoid using the touch-up tools, such as cloning and healing tools in Photoshop, or any feature that deliberately obscures manipulations.
Graphics downloaded from Web pages should not be used.
Please remember that Vector drawing data is absent from these files: png, jpeg, tiff, or bmp. Subsequently resaving any of these files as a PDF or EPS will not produce a vector drawing in these files. Please supply the original EPS, ai, or PDF file versions of artwork.
Figures/images should be inserted within the text as close as possible to where they are referenced. Authors should not upload them as separate files.
Acceptable digital formats are:
Unlocked PDFs created from a vector program
Microsoft PowerPoint, Excel, and Word as long as graphs are not placed into these programs as rasterized images
Arrange references as a simple list at the end of your manuscript based on our EndNote style which is downloadable through GMJ Medicine EndNote Style.
