Traditional Chinese medicine interventions based on meridian theory for pain relief in patients with primary dysmenorrhea: a systematic review and network meta-analysis
Abstract
ObjectiveTo determine the comparative effects and safety of traditional Chinese medicine (TCM) interventions based on meridian theory for pain relief in patients with primary dysmenorrhea (PD).MethodsThis is a systematic review with network meta-analysis. Randomized controlled trials (RCTs) comparing meridian-based TCM interventions with waitlist, placebo, western medicine, and conventional therapies for PD pain. A SUCRA was used to estimate the probability ranking for the effects of interventions.Results57 RCTs involving 3,903 participants and 15interventions were included. Thirty-two RCTs were rated as low risk of bias. A network diagram was drawn with 105 pairs of comparisons. Compared with NSAIDs and waitlist, significantly better effects were found in acupressure [SMD = −1.51, 95%CI (−2.91, −0.12)/SMD = −2.31, 95%CI (−4.61, −0.02)], warm needling [SMD = −1.43, 95%CI (−2.68, −0.18)/SMD = −2.23, 95%CI (−4.43, −0.03)], moxibustion [SMD = −1.21, 95%CI (−1.85, −0.57)/SMD = −2.10, 95%CI (−3.95, −0.07)], and acupuncture [SMD = −1.09, 95%CI (−1.62, −0.55)/SMD = −1.89, 95%CI (−3.67, −0.11)]. No adverse events were detected.ConclusionFor PD pain, the effects of acupressure, acupuncture, warm needling, and moxibustion were superior to those of NSAIDs and waitlist. Oral contraceptive pill, electro-acupuncture, acupressure, and warm needling demonstrated higher probabilities of being better interventions. More high-quality clinical trials are needed to provide more robust evidence of this network.Systematic review registrationPROSPERO CRD42022373312.
