Reviewers should seek clarification or decline the invitation if they perceive a significant conflict of interest (financial or otherwise) with the manuscript they are invited to review.
Confidentiality:
Reviewers must keep manuscripts and associated data confidential. If seeking advice from colleagues, reviewers must ensure confidentiality and provide the names of any consulted colleagues to the journal.
Anonymity:
Reviewers’ identities are not disclosed to authors to maintain impartiality. Reviewers are discouraged from revealing their identity, as they may need to comment on critiques and revisions from other reviewers.
