Guide for Authors

CJM follows ICMJE's Uniform Requirements for Manuscripts Submitted to Biomedical Journals and the Committee on Publication Ethics (COPE) as well as the World Association of Medical Editors (WAME) for manuscripts submitted to the journal.

Unsolicited manuscripts will be reviewed for publication with the following understanding:

  1. The paper represents an original work.
  2. The paper neither was published already nor is under review elsewhere.
  3. Upon acceptance, the paper may not be published elsewhere without the permission of Canon Journal of Medicine (CJM).
  4. The published paper is the sole property of CJM and may be edited before publication.

Open Access

CJM is an open-access journal distributed under the terms of the Creative Commons Attribution License (http://, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Users are free to copy and redistribute articles published in CJM in any medium or format under the Creative commons license terms and conditions.

Online Submission

CJM accepts manuscripts only through the online submission system, easy to use and easy to track. By conducting all procedures electronically, submissions will be made much faster. Once an article is submitted, it will be forwarded to an editor and, afterwards, to at least two peer reviewers. Immediately after submission, the author will be notified of the submission process by means of both email and a follow-up ID code issued to each article separately. It is recommended that the ID code be saved for all future correspondence regarding the submitted article.

Preparation of Manuscripts

Title Page: This should contain the title, running title, type of article, authors’ names and affiliations.

  • Running Title: A shorter version of the title (maximum 40 characters) is required. 
  • Type of Article: Based on the acceptable types of articles presented as following.
  • Authors’ Names: Full names (first, middle, and last) for all authors of an article should be given and specified with superscript number(s) for the affiliation(s) [e.g., Mark Junior Smiths1]. The name of the corresponding author(s) should be specified with an asterisk after the name (e.g., Mark Junior Smiths*). Where the family name may be ambiguous (e.g., a double name), please indicate clearly.

Manuscript Types

  • Editorial:

Editorials are the message of the CJM and are written in-house by the journal's Editorial Board members. Editorials are preferably no more than 2000 words and state-of-the-art-discussions on the CJM main scopes. An unstructured abstract is required for these types of articles. 

  • Original Articles:

These articles must be of primary research, methodologically accurate, and relevant to at least one aspect of clinical medicine or basic science. They should contain no more than 5000 words excluding structured abstract (maximum 250 words), tables, and references.

Note: Each clinical trial manuscript should have a specific trial registration code (IRCT, and ...) presented in the main body;otherwise, it will not be considered for further assessment in CJM.

  • Brief Report: 

Short reports should not exceed 3000 words and should contain a structured abstract (maximum 250 words).  The structure of a short report is similar to that of an original article but with some limitations: concise introduction, methods, results, discussion, conclusion, and up to 2 tables or figures.

  • Narrative Review Articles:

Only solicited review articles will be accepted. They should be upmost 5000 words, and contain unstructured abstract (maximum 250 words), introduction, authors’ comments and evidence, conclusion, recommendations for future, references (more than 50), and legends for display items (figures and tables).

Authors should report systematic reviews and meta-analyses in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement.

  • Case Presentation:

Only interesting and unique case reports with the following properties will be accepted:
word count up to 1500, structured abstract (maximum 250 words), introduction, (most importantly, the novelty of the case(s) report), then case presentation, followed by discussion and conclusion, references, and up to 2 figures or tables.

  • Letters to the Editor:

Letters to the Editor can be about a recent journal article a commentary article. There are some special limitations; the letters should be up to 500 words, have no figure or table, and use up to 5-7 references. No abstract is required for these articles. 



3-6 keywords must be provided in the keywords section at the end of the abstract. It is recommended that authors use the MeSH terms at:


Reference Style

All references in the text must be numbered consecutively, with each citation placed immediately after the term or phrase and usually before the period; they should appear like the following: [1, 2, 5, 6] or [7-9].

Some examples of the journal's reference style are provided below:

Unpublished work accepted for publication but not yet released should be included in the reference list with the words “in press” in parentheses beside the name of the journal concerned. References must be verified by the author(s) against the original documents.

Personal communications or manuscripts either “in preparation” or “submitted for publication” are unacceptable as a reference.

Note: Authors should write Authors’ Contributions, Conflict of Interest Disclosures, Funding/Support, and Ethical Approval/Consideration at the end of any type of article.


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 conflicts of interest. The potential for a 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 (if any) in their manuscript when submitting their work. The corresponding author is responsible for confirming with the co-authors whether they have any conflicts to be declared (For further information please visit ICMJE).


Ethical Considerations

CJM strictly follows the guidelines of the Committee on Publication Ethics (COPE); please visit COPE for information on publishing and ethical guidelines.

Please note that any submission including data collected from human subjects requires ethical approval. In this case, a clear statement 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 ethical approval, it 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 ethical approval (as sometimes occurs in resource-poor settings), the circumstances should be explained. Please anonymize the information as appropriate in the manuscript and give the information when asked during submission.

Author Agreement Form: This form should be completed and sent after acceptance. CJM could possibly ask for a data set (as an Excel or SPSS file) of the study related to the submitted article.

Tables: Tables should be created with a word processor (in simple form) and saved in either the DOC or RTF format. Tables must not be embedded in the text but provided on separate pages at the end of the manuscript and saved in DOC format.

Figures: To ensure the highest print quality, figures must be submitted in either TIF or EPS format according to the following minimum resolutions:

  • 1200 dpi (dots per inch) for black and white line art (simple bar graphs, charts, etc.)
  • 300 dpi for halftones (black and white photographs)
  • 600 dpi for combination halftones (photographs that also contain line art such as labeling or thin lines), figures should be saved as individual files. Vector-based figures (e.g., figures created in Adobe Illustrator) should be submitted in EPS format.

Color figures must be submitted in a CMYK color.

 Authorship Criteria

The International Committee of Medical Journal Editors (ICMJE) recommends the following criteria for authorship:

1. Substantial contributions to the conception and design or to the acquisition, analysis, or interpretation of the data;

2. The drafting of the article or critical revision for important intellectual content;

3. Final approval of the version to be published;

4. Agreement to be accountable for all aspects of the work ensuring that questions related to the accuracy or integrity of any part of the article are appropriately investigated and resolved.

Each author should meet all of the above-mentioned criteria to be listed in the submitted manuscript. Participation solely in the acquisition of funding or the collection of data does not justify authorship. General supervision of the research group is not sufficient for authorship. These contributors (non-author contributors) should be appreciated in the acknowledgment section, but not listed as co-authors.

The naming order of contributors should be based on the relative contribution of the contributor towards the study and writing of the manuscript. Once submitted, the order cannot be changed without the written consent of all contributors.


In case any attempt at plagiarism accompanied by convincing evidence is brought to our attention, the following steps will be taken:

  1. After consulting the respective Editorial Board members, the authors guilty of plagiarism will be debarred from publishing their papers in CJM.
  2. Heads of the Departments/Institutes of the offending authors will be informed of such incidences of plagiarism.
  3. In case of confirmation of plagiarism in an already published article, the editor will consider an article retraction based on COPE retraction guidelines.

Falsification and Fabrication

If the journal editor has clear evidence of fabrication (the intentional misrepresentation of research results by making up data) or falsification (manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record), he/she will consider an article retraction based on COPE retraction guidelines.
