Abstract
Introduction: Music therapy may have some potential in the pain control of extracorporeal shock wave lithotripsy, and this meta-analysis aims to study the analgesic efficacy of music therapy for extracorporeal shock wave lithotripsy.
Methods: We have searched several databases including PubMed, EMbase, Web of Science, EBSCO and Cochrane Library databases, and selected the randomized controlled trials (RCTs) comparing the efficacy of music therapy for pain control of extracorporeal shock wave lithotripsy. This meta-analysis was conducted using the random-effect or fixed-effect model based on the heterogeneity.
Results: Ten RCTs and 879 patients were included in this meta-analysis. Compared with routine care for extracorporeal shockwave lithotripsy, music therapy was associated with substantially reduced pain scores (standard mean difference [SMD] = -1.00; 95% CI = -1.57 to -0.42; P = .0007), improved patient satisfaction (SMD = 1.61; 95% CI = 0.45 to 2.77; P = .006) and willingness to repeat (SMD = 2.06; 95% CI = 0.40 to 3.72; P = .01), but had no influence on analgesic consumption (SMD = -3.11; 95% CI = -7.07 to 0.85; P = .12) or adverse events (OR = 1.66; 95% CI = 0.20 to 14.10; P = .64).
Conclusions: Music therapy was effective to control the pain of extracorporeal shock wave lithotripsy.

Unfortunately, the authors do not comment on the discrepancy of substantially reduced pain scores examined in 8 of 10 studies and no influence on analgesic consumption addressed in only 2 publications. Is it all statistics?
