The decision to withdraw a published Cochrane Review (or protocol) should generally be made between the authors and the Cochrane Review Group (CRG) editorial team. The reason for the withdrawal should be given in the Published Notes section of the protocol or review. When a protocol or review is withdrawn, it will be flagged in the published version in the Cochrane Database of Systematic Reviews (CDSR) as ‘withdrawn’ and only the title, coversheet, and reason for withdrawal will be published.
Published Cochrane Reviews (including protocols) are not removed from the CDSR. (Up to 16 December 2014, withdrawn protocols were removed from the CDSR after one issue of publication. From this date onwards, withdrawn protocols remain published to maintain the public record of publication and to complement the inclusion in PROSPERO.) A review may be withdrawn temporarily (suspended) and can be reinstated once it is considered satisfactory by the authors and the CRG's editorial team; otherwise it should remain withdrawn. Published versions that precede a withdrawn version are available in the CDSR by clicking on the ‘Other versions’ tab in the article.
Protocols that have not been converted into full Cochrane Reviews within two years of publication should generally be withdrawn from the CDSR.
