This journal follows a ‘double-blind peer review’ model. The primary purpose of this is to provide the Editor with the information needed to reach a fair, evidence-based decision that adheres to the journal's editorial criteria. Review reports should also help authors revise their paper such that it may be accepted for publication.

Editors are expected to independently verify the contact details of reviewers suggested by authors or other third parties. Institutional email addresses should be used to invite peer reviewers wherever possible. Each manuscript should be reviewed by at least two reviewers who were not suggested by the author.

Reviewers should express their views clearly with supporting arguments and references.

Reviewers should respect the confidentiality of material supplied to them and not discuss unpublished manuscripts with colleagues or use the information in their own work.
