Effect sizes were quantified as mean differences (MD) or standardized mean difference (SMD), with standard deviations (SD) of outcomes. An overall effect estimate was derived using a random-effects model when ≥ 2 studies reported similar outcomes. Statistical heterogeneity was assessed through the calculation of I² statistics. Additionally, a dose-response analysis was performed to assess potential dose-response relationships. Risk of bias was assessed using the Cochrane risk of bias tool for RCTs (RoB2.0).
