Subgroup analysis in RevMan


New Member
I am conducting a diagnostic test accuracy on RevMan and I have different index tests for different outcomes. I am comparing each outcome for each test and then I would like to compare paired test data. However, I am struggling to understand how I can actually use subgroup analysis on RevMan.
I have Sensitivity and Specificity for each test but sometimes for different groups (e.g low-risk, high-risk). I have tried to use the covariates method but my understanding is that it is useful only to assess heterogeneity.
How can I actually enter the Sensitivity and specificity for subgroups?
Thank you in advance,
