For observations of both EQ-5D-3L and CAT, there were a total of 4446 observations, and the numbers in each subset of the EQ-5D-3L range were as follows: EQ-5D < 0, 38; 0 ≤ EQ-5D < 0.25, 91; 0.25 ≤ EQ-5D < 0.5, 41; 0.5 ≤ EQ-5D < 0.75, 1617; 0.75 ≤ EQ-5D < 1, 1307; EQ-5D = 1, CAT, COPD assessment test; COPD, chronic obstructive pulmonary disease; EQ-5D, EuroQol five-dimensional questionnaire.
