Five RCTs with a total of 337 patients were included; 2 RCTs had low risk of bias. Two RCTs comparedyoga to usual care; 1 RCT compared yoga to exercise; and 2 3-arm RCTs compared yoga to usual care and exercise.No evidence was found for short-term effects of yoga compared to usual care on positive symptoms (SMD = −0.58;95% CI −1.52 to 0.37; P = 0.23), or negative symptoms (SMD = −0.59; 95% CI −1.87 to 0.69; P = 0.36). Moderateevidence was found for short-term effects on quality of life compared to usual care (SMD = 2.28; 95% CI 0.42 to4.14; P = 0.02). These effects were only present in studies with high risk of bias. No evidence was found forshort-term effects on social function (SMD = 1.20; 95% CI −0.78 to 3.18; P = 0.23). Comparing yoga to exercise, noevidence was found for short-term effects on positive symptoms (SMD = −0.35; 95% CI −0.75 to 0.05; P = 0.09),negative symptoms (SMD = −0.28; 95% CI −1.42 to 0.86; P = 0.63), quality of life (SMD = 0.17; 95% CI −0.27 to 0.61;P = 0.45), or social function (SMD = 0.20; 95% CI −0.27 to 0.67; P = 0.41). Only 1 RCT reported adverse events
