Within-group estimates and confidence intervals for five outcomes by treatment arm. The circles indicate standardized mean differences at 3 weeks compared to baseline and the boxes indicate standardized mean differences at 12 weeks compared to baseline, with the bars showing 75% and 95% CIs. Standardized mean difference values of 0.2, 0.5., and 0.8 refer to small, medium and large effects (Cohen, 1992)
