You must prepare your manuscripts in accordance with the "Uniform requirements for Manuscripts submitted to Biomedical Journal" developed by the International Committee of Medical Journal Editors in October 2001. The general and specific requirements of the JCDR are summarised below. Before sending a manuscript, contributors are requested to check for the latest instructions.
- Original articles : Randomised controlled trials, intervention studies, studies of screening and diagnostic tests, outcome studies, cost effectiveness analyses, case-control series, and surveys with a reasonably high response rate. Up to 3000 words excluding the abstract and the references.
- Review articles (including those related to the Ethics forum, the Education forum, E-Medicine, and so on): Systemic critical assessment of literature and data sources. Up to 4000 words excluding the abstract and the references.
- Case reports or briefs: Novel/interesting/extremely rare cases or rare presentations can be reported. Cases with clinical significance or implications will be given priority. Up to 1200 words excluding references and abstract and up to 10-15 references.
- Case Series : Same as case report more than two case reports having similar findings.
- Images in medicine : A short history, photograph, differential diagnosis, and discussion of a classic and/or rare case. Should not be more than 1000 words excluding up to ten references.
- Letter to the Editor : Should reflect short, decisive observation. Up to 500 words and five references.
- Clinicians Corner : Short narrative of a real life experience in the medical sphere during practice. Should contain a clear, informative, educative, or enlightening message. Up to 600 words.
- Short communications : An unusual or rare observation or a case study or a pilot study. Up to 1500 words.
- Announcements : of conferences, meetings, courses, awards, and other events of interest to the readers should be submitted with the name and address of the person from whom additional information can be sought. Up to 100 words.
- Book review : A sectional detailed analysis/observation of a book related to the scope and specialities covered in the journal. Up to 1500 words
To Justify authorship for the submitted manuscripts, the contributors should meet the following three conditions:
- Conception and design, acquisition of data, or analysis and interpretation of data has been done by the author
- Either drafting the article or revising it critically for important intellectual content has been done by the author
- The final approval of the version to be published has been given by the author. Each contributor should have participated sufficiently in the work to be allowed to take public responsibility for suitable portions of the content.
These are the guidelines given out by respected international bodies for authorship. Based on our experience we have add few points to the above which should also be taken into consideration while deciding upon the authorship list.
- Some articles are based on thesis works. In such cases, we expect both the Guide/Mentor and the Principal Investigator to be part of the authorship. In past we have faced post-publication authorship conflicts in which either of them were not included; hence the policy was introduced. If the corresponding author did not follow this, by excluding either or both the Principal Investigator and the Guide, they should attach a documental proof of consent whereby the individual has consented on the publication without his or her name in it as author. Interested readers can refer to the editorial publication based on such an incidence click here .
- In some articles author from departments unrelated to the topic of the article, from geographically separate institutions is seen. As incidences of gift or purchase authorship is high in the Indian subcontinent, such authors are viewed with contempt. And as a rule our editors tend to shy away from such articles, unless compelling argument is put forth by the corresponding author.
Naming Order for Contributors
The order of naming the contributors should be based on the relative contribution of the contributor towards the study and the writing of the manuscript. Once submitted, the order cannot be changed without the written consent of all the contributors.
Number of Contributors
In Original Articles (single institute-based or multi-centric studies), Research Protocols and, Systemic Reviews the number of contributors should not exceed eight. In exceptional cases, where the study is multicentric the number of authors in original articles (excluding Research Protocols) may exceed and the journal may accept the request, if the corresponding author provides a substantial justification. However, the decision is at the discretion of the Chief Editor. For Case Reports, Case Series and, Images in Medicine the number of contributors should not exceed five. For Letter to Editor the number of contributors should not exceed two. For Review of Literature the number of contributors should not exceed six.
No addition of author(s) will be entertained post submission. Exception to this will be made only with proper justification supported by institution/university head.
One or more author should take responsibility for the integrity of the work from the inception to the publishing of the article. This author will be designated as the guarantor.
Prerequisite for review articles
A review article can be written only by individuals who have done substantial work in a particular field. A short summary of the work done by the contributor(s) in the field of review should accompany the manuscript. The journal expects the contributors to provide post-publication updates on the subject of review. The update should be brief and should include the expected advancements in the field after the publication of the article. The update should be sent as a letter to the editor as and when major developments occur in the particular field.
All manuscripts for articles, original research reports, editorials, reviews, that are submitted to the journal must be accompanied by a conflict of interest disclosure statement or a declaration by the authors that they do not have any conflicts of interest to declare.
The Committee on Publication Ethics (COPE) states in its Guidelines on Good Publication Practice (2003) that:
‘Conflicts of interest arise when authors, reviewers, or editors have interests that are not fully apparent and that may influence their judgments on what is published. They have been described as those which, when revealed later, would make a reasonable reader feel misled or deceived.’
JCDR believe that, to make the best decision on how to deal with an article, Journal should know about any competing interests that authors may have, before an article can be reviewed and accepted for publication.
- Author must be truthful and must declare if the article has been published in some other language during the time of submission
- Author must disclose if some part of work has already been published or under consideration elsewhere.
- If the research submitted is the thesis or PhD work, author should reveal the name of the "Primary researcher" and the "Supervisor".
While reporting scientific project involving human subjects or experimental animals authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) or regulations for laboratory animals. The statement has to be mentioned in "Materials and Methods" section, right after the presentation of the study groups. We believe animal experimentation should be avoided whenever possible in favor of alternative research strategies.
Please use our Manuscript Management Portal : JCDR Pre Publishing for submitting manuscripts and knowing their post-submission status. For any problems related to submission please feel free to write to firstname.lastname@example.org
We do not accept print submission.
- Observational and experimental articles should be divided into sections, such as Introduction, Materials & Methods, Results, Discussion, References, Tables, Figures, Figure legends, and Acknowledgment.
- Use double spacing throughout.
- The language should be UK English.
Title page details to be filled in at the time of uploading the article on JCDR Pre Publshing.
The length of the abstract should be restricted to 250 words for case reports and brief reports and 350 words for original articles. For Original articles the abstract should be structured with the following sub-headings : Introduction, Aim, Materials and methods, Results and Conclusion. Case reports and case series should have unstructured abstract (no sub-headings). No abstract is required in Short communications, Images in Medicine, Letter to Editor.
These should be put in after reference to standard key words in Mesh terms.
State the purpose of the article and summarise the rationale for the study or observation. JCDR does not required Introduction in Case report, Images in medicine, View point and Letter to editor.

- Reports of random clinical trials should provide information regarding all major study elements, including the protocol, assignment of interventions, and the method of masking.(Click Here).
- Authors submitting review articles should include a section describing the methods used for locating, selecting, extracting, and synthesising data. These methods should also be summarised in the abstract.
- While reporting experiments on human subjects, you should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975 that was revised in 2013. (Click Here)
- Do not use names or initials of patients or hospitals and/or hospital telephone numbers especially in illustrative material.

- Emphasise the new and important aspects of the study and the conclusions that result from them.
- Do not repeat in detail the data or other material provided in the Introduction or Results section. Include in the Discussion section the implications of the findings for the present and for future research and their limitations. Relate the observations to other relevant studies.
- Contributors should refrain from commenting on economic benefits and costs unless their manuscript includes economic data and analyses.
- Avoid claiming priority and alluding to work that has not been completed.
- State new hypotheses when warranted, but clearly label them as such.
- Recommendations may be included only if appropriate.

- For scientific articles, contributors should obtain written permission and confirmation of accuracy from the source of a personal communication.
Tables & Figures
- JCDR was initially an online only journal later went into print. It does not differentiate between tables and figures in numbering them as images are made for both. All tables and Figures should be numbered in Arabic numerals consecutively in the order of their first citation in the text. ( example Table/Fig 1, Table/Fig 2......)
- Tables should be self-explanatory and should not duplicate textual material.
- Tables with more than 12 columns and 30 rows are not acceptable.
