IPES performance on predicting OS risk of stage I-III resected NSCLC patients. (a) and (b) Kaplan–Meier curves of the low- and high-risk subgroups predicted by IPES for stage I-III resected NSCLC patients in the (a) internal validation set and (b) external validation set. (c) and (d) Kaplan–Meier curves of the low- and high-risk subgroups predicted by IPES for resected NSCLC patients in (c) stage I and (d) stage II-III in the internal validation set. In the Kaplan–Meier curves, the horizontal axis represents survival time (months) and the vertical axis represents survival probability.
