If a Cochrane Review Group believes that the peer review process for a particular Cochrane Review will be significantly negatively impacted by using named peer review, the Managing Editor or Co-ordinating Editor may apply to the Network Senior Editor or Editor in Chief of the Cochrane Library for a policy exception on a review-by-review basis. In each case the Cochrane Review Group must provide details, including the reason for opting to remain anonymous. Any exemptions must be forwarded to the Cochrane Editorial & Methods Department (emd@cochrane.org); see Exceptions to named peer review: editorial management.
