Acupuncture Dosage and Its Correlation with Effectiveness in Patients with Chronic Stable Angina: A Systematic Review and Meta-Analysis of Randomized Controlled Trial.

To investigate the suitable dosage for CSA, we found that acupoints less than 5.8 may be significant in clinical treatment (SMD, −0.74, 95% CI [−1.11, −0.47], P <0.00001, I 2 =83%), intervention frequency is less than 4 times per week (SMD, −0.74, 95% CI [−1.09, −0.39], P <0.00001, I 2 =87%), and total sessions are less than 16 (SMD, −2.37, 95% CI [−2.84, −1.89], P <0.00001) may be a benefit in the clinical treatment.
