Breathing techniques to reduce symptoms in people with serious respiratory illness: a systematic review.

Comparison: yoga breathing versus usual care Yoga breathing reduced breathlessness measured with mMRC at 2–4 months compared to usual care, with the mean effect exceeding the MID of 1 point; however, this did not reach statistical significance (MD −1.05 points, 95% CI −2.45–0.35 points, three RCTs, n=175, I 2 =98%; supplementary figure S2 ).
