|---|---|---|---|---|---|
| CT volume measurements | Median value [L/%] | Range [L/%] | Median value [L/%] | Range [L/%] | p value |
| Healthy lung parenchyma | 2.69/74.38 | 5.01/72.40 | 4.19/90.86 | 2.43/14.1 | < < 0.01 |
| Emphysema parenchyma | 0.01/1.12 | 0.82/21.10 | 0.01/1.33 | 0.15/4.80 | > 0.05 |
| GGO | 0.64/19.50 | 1.63/56.50 | 0.21/5.67 | 0.25/10.80 | < < 0.01 |
| Consolidation | 0.03/1.06 | 0.08/2.70 | 0.03/0.70 | 0.03/0.6 | > 0.05 |
| Total volume | 3.80 | 3.90 | 4.55 | 2.20 | > 0.05 |
Note p value was evaluated for continuous variable by Mann–Whitney test and by chi-square test with Yates correction for categorical ones. The p values reported in bold were considered significant. % = percentage values of volumes with respect to the lung total volume
