Correlation between the six-gene signature and overall survival (OS) of patients in three datasets. a The distribution of risk scores, gene expression levels and patient survival status. b Kaplan–Meier curves of OS of low- and high-risk groups. c ROC curve for the 5-year survival prediction by the six-gene signature. The black dotted line in a represents the median risk score cut-off dividing patients into low- and high-risk groups
