The performance of the 5-gene prognostic model in TCGA dataset. A The survival status and expression of 5 genes of each sample ranked by risk score. The expression level was converted to z-score. Red indicates z-score > 0 and relatively high expression, while green indicates z-score < 0 and relatively low expression. B ROC curve of 1-year, 3-year and 5-year survival predicting. C Kaplan–Meier survival curve of high-risk and low-risk groups. Log-rank test was performed. AUC, area under ROC curve. CI, confidence interval. HR, hazard ratio
