BioImpacts Editors follows "the international standards for editors" recommended by COPE.
Authorship
The ICMJE recommends the authorship to be based on the following 4 criteria:
1. Substantial contributions to the conception or design of the work, or the acquisition, analysis or interpretation of data.
2. Drafting the work or revising it critically for important intellectual content.
3. Final approval of the version published.
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.
In addition to being accountable for the parts of the work he or she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their coauthors. All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors. Those who do not meet all four criteria should be listed in an Acknowledgements section. Participation solely in the acquisition of funding, the gathering of data, technical help, writing assistance, and general supervision of the research group does not warrant authorship. Financial and material support should also be acknowledged. Please guarantee that anyone stated in the Acknowledgements section has granted its clearance for permission to be listed.

Authors should meet "the international standards for authors" recommended by COPE.
