1. Change in COPD (chronic obstructive pulmonary disease) assessment test (CAT) score after pulmonary rehabilitation corresponding to different responses to the anchor question ‘How do you feel your overall condition has changed after rehabilitation?’: ‘much better’ n=162, ΔCAT −3.8±6.1; ‘a little better’ n=88, ΔCAT −1.3±4.5 (p<0.002).
Change in COPD (chronic obstructive pulmonary disease) assessment test (CAT) score after pulmonary rehabilitation corresponding to different responses to the anchor question ‘How do you feel your overall condition has changed after rehabilitation?’: ‘much better’ n=162, ΔCAT −3.8±6.1; ‘a little better’ n=88, ΔCAT −1.3±4.5 (p<0.002). As only small numbers were available for these categories, data for ‘no different’ n=8 ΔCAT −2.3±3.3; and ‘a little worse’ n=3 ΔCAT +2±0 are not shown.
