Principle Behind Manuscript Preparation
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.
Of Manuscript And Word Limits

To ensure authorship for the submitted manuscripts, the
contributors should meet the following three conditions:
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.
In the event of a study carried out in a single institute,
the number of contributors should not exceed eight. For case-reports,
images, letters to the editor, and review articles, the number
of contributors should not exceed five. There should be a
written justification if the number of contributors exceeds
five. If the JCDR feels necessary it may ask for description
of the contribution of authors towards the manuscript.
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.
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.

status. For any problems related to submission please feel free
