Assessing the performance of the prognostic risk model in the training and validation cohort. A, D Kaplan–Meier curves of the OS of patients in the high- and low-risk groups in the TCGA-STAD training cohort (A), and GSE66229 cohort (D). B, E ROC curves for predicting 1-, 3-, and 5-year OS in the TCGA-STAD training cohort (B), and GSE66229 cohort (E). C, F Distribution of risk score, survival status (red dots indicate dead, blue dots indicate alive) and the gene expression of 4 model genes in the TCGA-STAD training cohort (C), and GSE66229 cohort (F)
