Classification of the CFIP and TSCT findings
| Non-survivors | Survivors | p Value | |
|---|---|---|---|
| IPF/non-IPF | 19/13 | 11/8 | 0.94 |
| Extent of honeycombing (%) | 17±13 | 11±10 | 0.12 |
| Extent of GGO (%) | 56±15 | 49±15 | 0.10 |
| Distribution of GGO: diffuse/multifocal/peripheral | 29/1/2 | 12/1/6 | 0.0032 |
| CLE (±) | 7/25 | 11/8 | 0.015 |
| PSE (±) | 15/17 | 12/7 | 0.39 |
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.
