Pearson correlation coefficient heatmap for radiomic features and PFT/BGA indicators (A), and the distribution of PFT/BGA indicators between the low-risk and high-risk group (B-E). A. The FEV1/FVC% had modest correlation with three pulmonary features (SHAPE_Volume_mL, GLRLM_LRE and GLRLM_RP) (all Pearson correlation >|0.45|), and mild correlation with CONV_SUVstd of lungs and GLZLM_GLNUz of tumor (all Pearson correlation >|0.25|). Other PFT/BGA indicators and radiomic features were not well correlated. B-E. Patients in the low-risk group had better baseline FEV1/FVC% (median, 96.3% vs. 85.9%, p = 0.046) compared with those in the high-risk group. No significant difference of DLCO% (median, 84.3% vs. 77.5%, p = 0.136), pO2 (median, 86.0 vs. 86.0 mmHg, p > 0.999), AaDO2 (median, 18.0 vs. 18.0 mmHg, p > 0.999) and SaO2 (median, 96.8% vs. 96.5%, p = 0.634) was found. Abbreviation: PFT, pulmonary function test; BGA, blood gas analysis
