Use ‘What’s new’ events in Review Manager (RevMan) to describe the changes to the protocol or review since it was last published. What’s New events are used to help readers understand the type of change made to a new version of a Cochrane Review (or protocol for a Cochrane Review), such as an amendment, an update, and whether the conclusions have been changed or not. This is to ensure that the history of changes to a review remain with the review as new versions are published.
It is essential to select the appropriate option as set out in the following Tables, and to provide as much detail as possible to describe the nature of the change. The reasons for this are:
- To ensure a new citation is applied when appropriate. Note that assigning a new citation generates a new digital object identifier (DOI) and citation in external databases, including PubMed.
- To give readers clear information on what has changed between versions.
- To select the appropriate what’s new events before publication because these cannot be changed after publication (e.g. it is not possible to ‘undo’ a new citation).
Archie/RevMan guidance: While it is technically possible to enter several ‘What’s New’ events in an updated review, only information about the changes since the last published version must be in the ‘What’s New’ table. ‘What’s New’ events from previously published versions should be moved to the 'History' table in RevMan.

‘What’s New’ events for Cochrane Reviews
Type of change | Conclusions changed? | New citation version? | ‘What’s new’ events to select in RevMan |
---|---|---|---|
| Y | Y | (1) Updated* OR amended AND (2) New citation: conclusions changed |
| N | N | (1) Amended |
| N | Y | (1) Updated* OR amended AND (2) New citation: conclusions not changed |
* 'Updated' must only be used when a new search was completed AND studies were fully incorporated; see **.
** Studies are fully incorporated into the Cochrane Review if added to the included studies, excluded studies, ongoing studies, or studies awaiting classification (only if all reasonable efforts to integrate it into included, excluded, or ongoing have failed), or no new studies identified in search. Studies are not fully incorporated if studies identified by the search are added to studies awaiting classification only (see exception above). See ‘Reporting search dates’ for further information.
Withdrawing a published Cochrane Review
The withdrawal of a published Cochrane Review or a protocol for a Cochrane Review automatically creates a new citation version. To withdraw, see the policy and editorial management information, and follow the steps in Archie Help.
