Fig. 2From: Manipulation-induced hypoalgesia in musculoskeletal pain populations: a systematic critical review and meta-analysisForest plot comparing spinal manipulative therapy to sham for change in pressure pain threshold, in descending order of study quality. Abbreviations: CI = 95% confidence interval, SE = standard error, SMT = spinal manipulative therapy, CSMT = cervical SMT, TSMT = thoracic SMT, LSMT = lumbar SMT.
