Figure 4.Time-dependent receiver operating characteristic (ROC). ROC was used to evaluate the performance of prognostic models for 3-year (A) and 5-year (B) overall survival prediction in the discovery phase. ROC also was used to evaluate the performance of prognostic models for 3-year (C) and 5-year (D) overall survival prediction in the validation phase. C: clinical model; C+M+G: clinical, DNA methylation, and gene expression model.
