Validation of the 5-gene-based signature in the testing sets including GSE44295 and TCGA-UM datasets. A Kaplan–Meier curves of patients with UM in the low- and high-risk groups of the testing sets. B ROC curves for predicting accuracy of the 5-gene signature. C The risk scores and survival status of UM patients in the testing sets. D The comparison of the expression of the five genes in low- and high-risk groups in the two testing cohorts by Wilcoxon test
