Policy

Cochrane Reviews

From July 2019, Cochrane Reviews should only be withdrawn under exceptional circumstances (i.e. for reasons other than those that could be described using the Updating Classification System), for example, if there is a concern about the conduct or reporting of the Cochrane Review:

Examples of reasons for withdrawing a Cochrane Review

Withdrawal followed by republication

The Editors may accept for publication a revised version of a Cochrane Review that addresses the issues raised in the withdrawn notice. Any such version will be re-evaluated using standard Cochrane editorial process, and may then be approved for publication (as a separate, subsequent version) in consultation with the Editor in Chief.

Protocols for Cochrane Reviews

Protocols that have not been converted into full Cochrane Reviews within two years of publication should generally be withdrawn from the CDSR.

Up to 16 December 2014, withdrawn protocols were removed from the CDSR after one issue of publication. From this date onwards, withdrawn protocols remain published to maintain the public record of publication and to complement the inclusion in PROSPERO.

Published Cochrane Reviews (including protocols) are not removed from the CDSR when they are retracted or archived using the “withdrawn” publishing event. (Up to 16 December 2014, withdrawn protocols were removed from the CDSR after one issue of publication. From this date onwards, withdrawn protocols remain published to maintain the public record of publication and to complement the inclusion of protocols in PROSPERO[change link to point to EPPR Prospero].) A Cochrane Review may be retracted temporarily (suspended) and then republished once it is considered satisfactory by the authors, the CRG's editorial team, and the Editor in Chief; otherwise it will remain retracted. Published versions that precede a retracted/archived version are available in the CDSR by clicking on the ‘Other versions’ tab in the article.

The publication of a retraction (withdrawn) statement generates a new citation version. For Cochrane Reviews, this includes a new entry in PubMed.

What displays in the published version?

When a protocol or review is withdrawn, it will be flagged in the published version in the Cochrane Database of Systematic Reviews (CDSR) as ‘withdrawn’.

Published Cochrane Reviews (including protocols) are not removed from the CDSR. Published versions that precede a withdrawn version are available via the 'History' section of the Cochrane Review.

The following information is included in the withdrawn version:

• Reason for withdrawing the protocol/review (as inserted in the “Published Notes” section in the RevMan file), preceded by "Reason for withdrawal from publication".
• Standard publication information: title, authors (as listed on previous citation version), citation, DOI, publication date, editorial group name, Sources of support (as listed on previous citation version), and publishing events (What’s new and History).
• The following text is inserted automatically at the end of the “Reason for withdrawing this protocol/review” text: “The editorial group responsible for this previously published document have withdrawn it from publication.”
• Citations for the withdrawn version, as available via Crossref Cited-by Linking.
• Published versions that precede a withdrawn version are available in the CDSR by clicking on the ‘Version History’ tab in the article.

What displays in the PubMed record?

• Article title preceded by "WITHDRAWN:".
• Abstract of the version that has been withdrawn.

Steps to withdraw a Cochrane Review

When withdrawing a Cochrane Review, three steps need to be taken: (1) notify the authors; (2) draft the withdrawn statement; and (3) notify the Editorial & Methods Department.

Step 1. Notify authors

The Managing Editor should notify the contact author (with copies to all co-authors) of the intention to withdraw the Cochrane Review – and give the opportunity for discussion (unless authors are not contactable) –  before proceeding with publication of the withdrawn statement.

If contactable, the authors must be asked if they agree with the proposed withdrawal, as this information can be included in the withdrawn statement.

Step 2. Draft the retraction/archive statements

In keeping with the Committee on Publication Ethics (COPE) Guidelines for retracting articles, the published reason for withdrawal must not be potentially defamatory or libelous. Also see “What should an ideal retraction notice look like?”from Retraction Watch for further reading.

Note that the Editor in Chief must approve all retraction statements before publication. See Step 3 below.

Statement to accompany the withdrawn Cochrane Review

The withdrawn statement must include the following information:

1. Reason(s) for withdrawal, starting with: “This Cochrane Review has been withdrawn from publication.”
2. Which section(s) of the review is/are affected.
3. Who is withdrawing the review (and whether the authors agree).
4. Whether the Cochrane Review will be revised and re-published in future.

Statement to accompany the retracted (withdrawn) protocol for a Cochrane Review

The withdrawn statement must include the following information:

1. Reason(s) for withdrawal, starting with: "This protocol for a Cochrane Review has been withdrawn”.
2. Who is withdrawing the protocol (and whether the authors agree).
3. Whether the protocol will be revised and republished in future.

Step 3. Notify Editorial & Methods Department

The Editor in Chief (ceu@cochrane.org) must approve all retraction notices before publication. Provide the:

• Title
• DOI of the version being withdrawn
• Reason for withdrawal

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.
