Table 4. Factors associated with the amount of annual FVC decline in patients with NTM pulmonary disease, by linear regression analysis.
Variables | Beta | p value | 95% C.I. |
M. kansasii pulmonary disease | 0.227 | 0.062 | −0.342–−0.008 |
Baseline pulmonary function: FEV1>50% vs. FEV1≤50% | 0.263 | 0.032 | 0.012–0.263 |
NOTE. NTM, non-tuberculous mycobacteria; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second.
