As per ICMJE guidelines the authorship should be based on the following criteria:
1. Substantial contributions to conception & design, or acquisition of data, or analysis & interpretation of data.
2. Drafting the article or revising it critically for important intellectual content.
3. Final approval of the version to be published. All those who meet the above three conditions are eligible to
be included as Authors in the manuscript
4. 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 work are appropriately investigated and resolved.
When a large multicenter group has conducted the work, the group should identify the individuals who
accept direct responsibility for the manuscript. These individuals should fully meet the criteria for authorship/
contributorship defined above. Acquisition of funding, collection of data, general supervision of the research
group does not qualify any one to be an author. All contributors who do not meet the criteria for authorship
should be listed in the acknowledgment section. Those who provide technical support, writing assistance, or
department chair who provided just general support should also be mentioned in acknowledgment. It is also
important that all those whose names appear in acknowledgement must have given permission to be acknowledged
