This report, titled "Evolution of Cochrane Intervention Reviews and Overviews of Reviews to better accommodate comparisons among multiple interventions" summarizes a meeting held in Milan in March 2011 and hosted by the Italian Cochrane Centre.

In addition to methodologists with an interest in comparing multiple interventions, participants included five Co-ordinating Editors, a recent Managing Editor, a Trials Search Coordinator, a Field Convener, a Centre Director, authors of Overviews of Reviews and Intervention Reviews, and the Editor in Chief.

The report (available on the CMIMG website) summarizes the outputs of the meeting, providing a new proposed strategy for ensuring that comparisons among multiple interventions are provided in a sound and meaningful manner within the Cochrane Database of Systematic Reviews (CDSR).

We are very interested in receiving feedback on this report and would value your comments using the forum topic we have created or via direct communication with one of the co-convenors.
