*3.3. Primary Outcome (Movement Function, UPDRS-III): PMA*

In PMA of movement function evaluated by UPDRS-III, statistical significance was shown between the following comparisons presented with MD and 95% CI **(in favor of bold marks):** (1) **electroacupuncture + CM (ELEC)** vs. CM (CONV) (MD −3.63, 95% CI −6.05 to −1.21); (2) **manual acupuncture + CM (MANU)** vs. CONV (MD −3.90, 95% CI −6.24 to −1.57); (3) **electroacupuncture + CM (ELEC)** vs. sham acupuncture + CM (SHAM) (MD −18.10, 95% CI −30.31 to −5.89). In other comparisons, such as BVA + CM (BEEV) vs. CONV, MANU vs. SHAM, and BEEV vs. SHAM, the acupuncture modality tended to be more effective than the control group, but the difference was not statistically significant. Detailed descriptions of the effect size and each trial-based forest plot are provided in Supplementary Materials Digital Content 4.
