  • Comparison between groups was performed by Mann-Whitney's U test (for continuous variables) or the χ2 test (for categorical variables).

  • CFIP, chronic fibrosing interstitial pneumonia; CLE, centrilobular emphysema; GGO, ground-glass opacity; IPF, idiopathic pulmonary fibrosis; PSE, paraseptal emphysema; TSCT, thin-section CT.
