title: [Lack of clear guidelines for authorship in multicentre studies].
abstract: Determining authorship in multicentre studies can be difficult because of the large number of contributors and collaborators. Different experiences and recommendations regarding authorship and byline listing emphasize the importance of transparency and communication before, during, and after manuscript preparation. More specifically, written publication policies, regular meetings, and different scoring systems can be considered. It is important to reduce potential disincentives for engaging in multicentre studies. Therefore, clear guidelines for authorship assignment are necessary.
