1. Risk Differences (RD) estimated for the probability of improvement. The Regular Exercise and Asthma Control Trial [REACT].
2. aIn the past 4 weeks, how much of the time did your asthma keep you from getting as much done at work, school or at home? All of the time (1 point); Most of the time (2); Some of the time (3); A little of the time (4); None of the time (5 points).
3. bDuring the past 4 weeks, how often have you had shortness of breath? More than once a day (1); Once a day (2); 3 to 6 times a week (3); Once or twice a week (4); Not at all (5).
