Acupuncture for the treatment of trigeminal neuralgia: A systematic review and meta-analysis
Abstract
BACKGROUND AND PURPOSE
Few systematic reviews have examined the effects of acupuncture on trigeminal neuralgia. This review aims to provide up-to-date evidence on the efficacy of acupuncture for managing pain in patients with trigeminal neuralgia.
METHODS
Eleven databases were searched from inception until November 2022 for relevant articles Two researchers independently conducted study selection, data extraction, and evaluation. The present review solely targeted randomized controlled trials (RCTs). The Cochrane risk of bias assessment tool 2.0 was employed to assess the risk of bias. Data were compiled using RevMan 5.4.1 software, and the quality of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.
RESULTS
Thirty studies involving 2295 patients were included in this review. Compared with carbamazepine, acupuncture led to improvements in pain scores (15 RCTs, mean difference (MD) - 1.40, 95% confidence interval (CI)-1.82 to -0.98 [95% prediction interval, -3.137,0.343], p < 0.00001, low certainty of evidence (CoE)), response rates (29 RCTs, risk ratio (RR) 1.20, 95% CI 1.15 to 1.25 [95% prediction interval, 1.067, 1.346], p < 0.00001, low CoE), frequency of pain attacks (2 RCTs, MD -2.53, 95% CI -4.11 to -0.96, P = 0.002, low CoE), and adverse effects (13 RCTs, risk difference (RD) -0.15, 95% CI -0.19 to -0.11 [95% prediction interval, -0.193, -0.108], P < 0.00001, very low CoE).
