Fig. 2 Pooled SMDs and 95% CIs for the analgesic treatment effect of NSAIDs and opioids, by pain modality. Positive increasing SMDs indicate analgesic efficacy. Thermally-evoked pain with only two observations from one study was excluded from the analysis. One study may involve the testing of more than one pain modality and/or drug. Forest plots for each subgroup are presented in Appendix 5.
