(A) Risk-of-bias (ROB) quality ratings for the randomized-controlled trials (RCT), (B) forest plot for general social anxiety (SA) symptomatology for clinical (CL) and non-clinical (NCL) samples, and (C) for fear of negative evaluation (FNE). ROB was assessed by means of the “Quality Assessment Tool of Controlled Intervention Studies” from the National Heart, Lung, and Blood Institute (2019). Negative effect sizes indicate that symptomatology was lower in the PA treatment than in the control group.
