Note: Quantitative data were presented as mean ± SD (min – max). Friedman test showed significant difference of the CT score among right upper lobe, right middle lobe and right lower lobe (P < 0.01); Wilcoxon test showed significant difference of the CT score between left upper lobe and left lower lobe (P < 0.01); Kruskal-Wallis test showed significant difference of the CT score among different stages (P < 0.01). Differences were considered significant at P < 0.05.
