CRediT author statement

CRediT (Contributor Roles Taxonomy) was introduced with the intention of recognizing individual author contributions, reducing authorship disputes and facilitating collaboration. The idea came about in 2015 at a Harvard workshop and it became a collaborative effort led by the Wellcome Trust and Digital Science, with input from publishers, including Elsevier, represented by Cell Press.

CRediT offers authors the opportunity to share an accurate and detailed description of their diverse contributions to the published work.

  • The corresponding author is responsible for ensuring that the descriptions are accurate and agreed by all authors.
  • The role(s) of all authors should be listed, using the relevant above 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.
