Verification of the effectiveness of the model. A–E Kaplan-Meier curve for survival analysis. F–J The ROC curve of 5-year follow-up time. A, C, F, H The results in the training set. B, D, G, I The results in the internal validation set. E, J The results in GSE19234. The clinical outcome endpoint in A, B, E, F, G, J was PFI. The clinical outcome endpoint in C, D, H, I was OS. AUC, area under curve; PFI, progression-free interval; OS, overall survival. And P < 0.05 is defined as statistically significant
