Authorship Criteria

As stated in the International Committee of Medical Journal Editors (ICMJE) Recommendations, credit for authorship requires:
?Substantial contributions to the conception and design, or the acquisition, analysis, or interpretation of the data;
?The drafting of the article or critical revision for important intellectual content;
?Final approval of the version to be published;
?Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the article are appropriately investigated and resolved.
Authorship credit should be based only on substantial contributions to each of the four components mentioned above.
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. Each contributor should have participated sufficiently in the work to take public responsibility for appropriate portions of the content of the manuscript. The order of naming the contributors should be based on the relative contribution of the contributor towards the study and writing the manuscript. Once submitted the order cannot be changed without written consent of all the contributors. Manuscripts must be submitted by one of the authors of the manuscript, and should not be submitted by anyone on their behalf. The corresponding author takes responsibility for the article during submission and peer review.

Changes in authorship

Authors should determine the order of authorship among themselves and should settle any disagreements before submitting their manuscript. Changes in authorship (ie, order, addition, and deletion of authors) should be discussed and approved by all authors. Any requests for such changes in authorship after initial manuscript submission and before publication should be explained in writing to the editor in a letter or email from all authors and should send the original signed written consent of all authors with authorized unit stamp.

Contribution details

Contributors should provide a description of contributions made by each of them towards the manuscript. Description should be divided in following categories, as applicable: concept, design, definition of intellectual content, literature search, clinical studies, experimental studies, data acquisition, data analysis, statistical analysis, manuscript preparation, manuscript editing and manuscript review. One author should take responsibility for the integrity of the work as a whole from inception to published article and should be designated as ‘corresponding author’.
