Fig. 2: Effect size of the yoga intervention compared to the minimally important difference (MID) with 95% confidence interval.

The effect size was calculated as the difference between the postintervention score minus the preintervention score in the yoga group and the postintervention score minus the preintervention score in the control group. The MID was calculated as one-third of the overall standard deviation of the patient-reported scale item at baseline. The ⊗ mark on the graph indicates the MID for the scale item.
