The study evaluates the effectiveness of acupuncture-related therapies for chronic cough caused by gastroesophageal reflux disease (GERC), where conventional treatment with proton pump inhibitors is often insufficient. They systematically searched 11 databases up to June 2025 and analyzed five randomized controlled trials with 390 patients. Acupuncture combined with Western medicine significantly reduced daytime cough (MD = -0.41, 95% CI [-0.75, -0.07]) and nighttime cough (MD = -0.38, 95% CI [-0.59, -0.17]) scores. The Leicester Cough Questionnaire score also improved (MD = 2.29, 95% CI [1.99, 2.60], p < 0.00001) and the overall effective rate was higher (RR = 1.13, 95% CI [1.01, 1.27]). No serious adverse events were reported. The risk of bias was moderate, mainly due to blinding and allocation. Evidence is limited, larger high-quality studies are needed.
