Summary of the evidence for efficacy and risk of bias from trials included in key systematic reviews of drugs for pain in patients with RA. Where efficacy is green, this indicates there is trial evidence indicating a favourable effect on pain (please see manuscript text and Table 1 for details on effect sizes). Where efficacy is orange, this indicates there is uncertain trial evidence for a favourable effect on pain. Where risk of bias is red, this indicates the trial evidence is at high risk of bias. Where risk of bias is orange, this indicates the trial evidence is at variable risk of bias. Where risk of bias is green, this indicates the trial evidence is at low risk of bias. Please see Table 1 for further details on each systematic review considered in this figure
