Linear model of residual volume (RV)/total lung capacity (TLC) against visual low-density lobule score, visual fibrosis extent and visual emphysema extent
| β-estimate±se | p-value | |
| Low-density lobules | 2.01±0.42 | <0.001 |
| Fibrosis | 0.28±0.20 | 0.16 |
| Emphysema | 0.09±0.25 | 0.73 |
Includes 73 patients with RV/TLC available. Adjusted R2=0.29, p<0.001. p<0.05 was considered significant.
