Independent relationships between computed tomography measurements and the lung function measurements shown to correlate with mortality
| Parameters | RC (95% CI)# | p-value |
| TLC % pred | ||
| Mosaicism | 0.41 (0.06–0.75) | 0.02 |
| RV/TLC % pred log¶ | ||
| Wall thickness | 0.02 (0.01–0.02) | <0.0005 |
| Mosaicism | 0.01 (0.01–0.02) | 0.001 |

| Emphysema | -0.85 (-1.4– -0.30) | 0.003 |
RC: regression coefficient; CI: confidence interval; TLC: total lung capacity; % pred: % predicted; RV: residual volume; KCO: transfer coefficient of the lung for carbon monoxide. #: RC >0 describes a positive correlation between the parameter measurements, whereas RC <0 suggests a negative correlation; ¶: log transformed (log 56.93) to correct for skewness.
