After adjustment for baseline values, 12-week outcomes for the yoga group were superior to those for the self-care group (mean difference for function, −2.5 [95% CI, −3.7 to −1.3]; P < .001; mean difference for symptoms, −1.1 [95% CI, −1.7 to −0.4]; P < .001). At 26 weeks, function for the yoga group remained superior (mean difference, −1.8 [95% CI, −3.1 to −0.5]; P < .001). Yoga was not superior to conventional stretching exercises at any time point.
