| Total CT score of the pulmonary involvement | 2 ± 4 (0-18) | 5 ± 5 (0-22) | 7 ± 7 (0-22) | 7 ± 7 (0-25) | 5 ± 7 (0-24) | 4 ± 6 (0-25) | < 0.00011 |
| Number of involved lobes | 22 ± 2 (0-5) | 3 ± 2 (1-5) | 4 ± 2 (1-5) | 3 ± 2 (1-5) | 3 ± 2 (1-5) | 4 ± 2 (1-5) | < 0.00011 |
| CT score in each lobe | < 0.00011 | ||||||
| Left upper lobe | 0 ± 1 (0-3) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-4) | 1 ± 1 (0-5) | |
| Left lower lobe | 1 ± 1 (0-5) | 1 ± 2 (0-5) | 2 ± 2 (0-5) | 2 ± 1 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | |
| Right upper lobe | 0 ± 1 (0-3) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | |
| Right middle lobe | 0 ± 1 (0-3) | 1 ± 1 (0-5) | 1 ± 2 (0-5) | 1 ± 2 (0-5) | 1 ± 1 (0-5) | 0 ± 1 (0-5) | |

Quantitative data were presented as mean ± SD (minimum-maximum). Mann-Whitney U test showed significant difference between Stage-1 and Stage-2-6 (P < 0.05); Wilcoxon test showed significant difference between the left lower lobe and the left upper lobe (P < 0.05); Wilcoxon test showed significant difference between the right lower lobe and the right upper/middle lobe (P < 0.05).
