Results:
We systematically reviewed 44 randomized controlled trials (involving 5022 patients through June 2018). Auricular acupressure plus antihypertensive drugs might be more effective than antihypertensive drugs alone in both reducing systolic blood pressure value after treatment (n=464 patients; mean difference, −5.06 mm Hg; 95% confidence interval, –6.76– −3.36, p<0.00001; I2=32%), decreasing diastolic blood pressure after treatment (n=464 patients; mean difference, −5.30 mm Hg; 95% confidence interval, –6.27– −4.33, p<0.00001; I2=0%) and the efficacy rate (relative risk, 1.22; 95% confidence interval, 1.17–1.26; p<0.00001; I2=0%).
