The ROB-MEN tool to evaluate the risk of bias due to missing evidence in network meta-analysis

These videos, originally part of the Cochrane Learning Live webinar series, present the ROB-MEN framework and demonstrate the web application (available here) through an example. The audience was able to learn how to assess the risk of bias due to missing evidence (i.e. evidence missing due to unpublished studies and/or selective outcome reporting) in the network estimates using ROB-MEN.

The session consisted of a short introductory presentation followed by a live demonstration of the sofware with pauses for Q&A. It was aimed at people who have undertaken a systematic review that includes a network meta-analysis, or were interested in doing so.

The webinar was delivered in May 2022 and below you will find the videos from the webinar, together with accompanying slides to download [PDF].
