Data are presented as mean ± standard deviation.
CT, computed tomography.
1Mann–Whitney U test showed a significant difference between Stage A and Stage B (P < 0.05).
2Wilcoxon test showed a significant difference between the right upper lobe and right lower lobe (P < 0.05).
3Wilcoxon test showed a significant difference between the right middle lobe and right lower lobe (P < 0.05).
4Wilcoxon test showed a significant difference between the left upper lobe and left lower lobe (P < 0.05).
5Mann–Whitney U test showed a significant difference between Stage C and Stage B (P < 0.05).
6Mann–Whitney U test showed a significant difference between Stage C and Stage D (P < 0.05).
