Figure 3.

Frequency of rescue medication use in yoga and control groups. Rescue medication use was calculated as an average use of short acting β2-agonists per day (puffs/day) for 2 wk, hence, there are five time points. There is significant overall decline in rescue medication use in both yoga (p < .001) and control groups (p < .05). Also significant differences seen at 2 wk (p < .05) and 4 wk (p < .01) between yoga and control groups.
