Tables and Figures

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.


  1. 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, the following general principles must 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.


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).

 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 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 
  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.

All the accepted manuscripts will undergo plagiarism screening using iThenticate software upon preliminary acceptance.


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.


  1. Repository Policy of the Journal

As per the Journal’s Open Access Policy, authors are entitled of making final accepted or published version of their article available publicly in various domains and repositories according to the terms of the CC BY license. The final version of the author’s paper and the pre-review version might be solely available on pre-print repositories. 

When reusing, distributing, posting or archiving articles, the journal must be attributed clearly as the original publication authority and correct details of citation must be provided. Authors are therefore required to deposit the unique URL/DOI of their published article in addition to the Version of Record in any Repository. We encourage authors to self-archive and submit their papers in institutional repositories or on their websites without embargo. These practices ensure greater citation of published work and provide productive exchange benefits to the authors.


  1. Peer-Review process

CJM adheres to a double-blind peer-review process that is rapid, fair, and ensures the high quality of published articles. CMJ's reviewers are required to declare their conflicts of interest and maintain the confidentiality of the manuscripts they review. As CJM is a rapid response journal, the review process takes 3 weeks at the utmost. Reviews will be published along with the articles to ensure clarity and transparency. Here is a brief description of the peer-review process in CJM, you can find more information here.
