Interventions used in control group against cupping therapy for chronic nonspecific low back pain: A systematic review and network meta-analysis
Abstract
Introduction: The evidence for the effect of cupping therapy on chronic nonspecific low back pain (CLBP) remains controversial, and existing researches didn't consider outcomes influenced by factor of selection of interventions in control group. This review and network meta-analysis is to compare the effects of diverse interventions in cupping therapy control groups for CLBP, with the objective of identifying the suitable control intervention against cupping therapy for CLBP.
Methods: Studies were identified by a comprehensive search of databases, such as PubMed, Embase, Cochrane Library, Web of Science and China National Knowledge Infrastructure (CNKI), up to June, 2024. A total of 10 randomized control trials (RCT) were included in this network meta-analysis (NMA).
Results: The results showed that compared with cupping therapy, minimum negative pressure cupping therapy (MNPCT) (SMD = - 0.01; 95 %CI: - 0.92 to 0.89), air circulating cupping therapy (ACCT) (SMD = - 0.05; 95 %CI: - 0.63 to 0.54) and diclofenac (SMD = - 0.13; 95 %CI: - 1.13 to - 0.87) was no significantly different from improvement of pain intensity. But there was significant difference between cupping therapy and D-ibuprofen (SMD = - 1.11; 95 %CI: - 2.08 to - 0.13), paracetamol (SMD = - 1.12; 95 %CI: - 1.80 to - 0.43) or usual care (SMD = - 1.18; 95 %CI: - 2.56 to - 1.06). The order of intervention effect by SUCRA diagram was as follows: cupping therapy (77.7 %) > MNPCT (75.2 %) > ACCT (73.8 %) > diclofenac…
