Editorial processes for Cochrane reviews, through peer review to publication, are now done by the Central Editorial Service.

Cochrane invites prospective authors to propose new Cochrane Reviews by submitting a proposal in Editorial Manager. Please see the Cochrane Library information for authors for further details.

Cochrane can reject a Cochrane Review at any stage before publication (including unpublished protocols, unpublished Cochrane Reviews, and Cochrane Reviews that are being updated).  Authors should note:

• Registration of a new title or drafting of the protocol for a Cochrane Review by a specific author team does not guarantee publication for that team. Publication of a protocol does not guarantee authorship or publication of the subsequent review; and publication of a Cochrane Review does not guarantee authorship or publication of an updated version.
• Authors are free to submit elsewhere a Cochrane Review that has been rejected on the condition that no reference is made to the manuscript being a Cochrane Review.
