New functionality is now available in RevMan Web extending the number of ways data can be inputted when raw data from study reports does not match the format required for meta-analysis. Data entered into the calculator will also now be saved along with the calculated output, which will allow authors to better document how raw data have been transformed to support verification, transparency, and updating. Analyses will show a tick under a calculator icon to indicate where calculations were required.

The Knowledge Base has been updated with information about how to use the new functionality, the types of transformation that are now supported, and actions that authors should be aware of that could result in saved data being lost.

Feedback about the calculator functionality is welcome and should be directed to support@cochrane.org.
