Author Contributions

CRediT Author Statement

CRediT (Contributor Roles Taxonomy) was introduced to recognise individual author contributions, reduce authorship disputes and facilitate collaboration. The idea followed a 2012 collaborative workshop led by Harvard University and the Wellcome Trust, with input from researchers, the International Committee of Medical Journal Editors (ICMJE) and publishers, including Elsevier, represented by Cell Press.

CRediT allows Authors to share an accurate and detailed description of their diverse contributions to the published work.

The corresponding Author is responsible for ensuring that all authors agree with accurate descriptions.
All authors' role(s) should be listed using the above relevant categories.
Authors may have contributed in multiple roles.
CRediT in no way changes the journal's criteria to qualify for authorship

CRediT statements should be provided during the submission process and will appear above the acknowledgement section of the published paper, as shown further below.
