Annual pre-BD lung function decline from Max0-2.5 to follow-up by physical activity group.
| ≤240 min of physical activity/day | >240 min of physical activity/day | p-value* | |
|---|---|---|---|
| ΔFVC/year, pre-BD (ml) | −43.6 (42.1) | −29.3 (39.7) | 0.018 |
| ΔFVC/year, pre-BD (%) | −0.12 (1.14) | 0.03 (0.95) | 0.325 |
| ΔFEV1/year, pre-BD (ml) | −58.8 (37.3) | −41.4 (34.2) | 0.001 |
| ΔFEV1/year, pre-BD (%) | −0.83 (1.13) | −0.39 (0.97) | 0.005 |
| ΔFEV1/ΔFVC -ratio/year, pre-BD | −0.0052 (−0.0101 to −0.0019) | −0.0041 (−0.0075 to −0.0016) | 0.062 |
*Statistical significances were evaluated using Mann-Whitney test or independent samples t-test. Results are displayed as median (interquartile range) or mean (SD). FVC: forced vital capacity, BD: bronchodilator, FEV1: forced expiratory volume in 1 s.
