The predictive performance of the risk score and other clinicopathological parameters. (A–H) The univariate and multivariate Cox regression suggested that the risk score was an independent prognostic factor in the training and validation sets. The red, blue, green, and yellow dashed boxes corresponded to the TCGA, GSE13507, GSE32548, and GSE48075, respectively. I, J, K, and L showed that the 1-year multiple ROC curves of the risk score and other clinicopathological parameters in the training set, GSE13507, GSE32548, and GSE48075, respectively. M, N, O, and P showed that the 3-years multiple ROC curves of the risk score and other clinicopathological parameters in the training set, GSE13507, GSE32548, and GSE48075, respectively. Q, R, S, and T showed that the 5-years multiple ROC curves of the risk score and other clinicopathological parameters in the training set, GSE13507, GSE32548, and GSE48075, respectively.
