The research is strictly guided by the academic practices stated in the Vancouver Protocol.
Authorship credit should be based only on substantial contributions to:
a) conception and design, or analysis and interpretation of the data; and to
b) drafting the article or revising it critically for important intellectual content; and on
c) final approval of the version to be published.
Conditions a), b), and c) must all be met.
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. Any part of an article critical to its main conclusions must be the responsibility of at least one author.
All of the research partners should agree on these conditions before participation in the research.
