Comparison of model performance among the combined, radiomic, and clinical models. AUCs and C-indices based on the three optimal probabilities were evaluated with bootstrap resampling 100 times. Red, green, and blue lines correspond to C-index from the combined, radiomic, and clinical models, respectively. (a) AUCs in the combined model have the best performance at three time points. The combined model showed significantly higher AUCs than the other models. (b) C-indices in the combined model have the best performance at three time points. The combined model showed a significantly higher C-index than the other models. 95% CI: 95% confidence interval; Red: 8 months; Green: 12 months; Blue: 24 months; ***: p < 0.001.
