From: ROB-MEN: a tool to assess risk of bias due to missing evidence in network meta-analysis
Signalling question | Responses for each comparison (groups A and B only) | ||
|---|---|---|---|
1. Was there any eligible study for which results for the outcome of interest were unavailable, likely because of the p-value, magnitude or direction of the result generated? | Yes | Yes | No |
2. (If Yes to the previous question) Was the amount of information omitted from the synthesis sufficient to have a notable effect on the magnitude of the synthesised result? | Yes | No | - |
Overall judgement | Suspected bias (favouring X) | No bias detected | No bias detected |
