Change from baseline in outcome measures
| End of intervention | Two months after intervention | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| n | Yoga | Control | Difference* (95% CI) | p value | n | Yoga | Control | Difference* (95% CI) | p value | |
| AQLQ = asthma related quality of life questionnaire; FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; PD20FEV1 = dose of methacholine provoking a fall in FEV1 of 20% or more. *Change in yoga group – change in control group, differences tested by unpaired (two sample) t test. |
