The results of multivariate analysis indicated that E/IMLD was significantly associated with sedentary behavior (EX < 1.5) in patients with COPD, with an adjusted OR of 0.39 (95% CI, 0.16–0.95; p = 0.04) when accounting for age, CAT score, predicted %FEV1, and %DLCO (Table 4). Here, CAT is linked to chronic obstructive pulmonary disease.
