Kaplan–Meier survival curves of patients in high- and low-risk groups and ROC curves of the risk model a Kaplan-Meier survival curves show the effect of the 5-gene risk score on OS of patients with GC. The blue line represents low-risk group and the red line represents high-risk group; b ROC curves for assessing the sensitivity and specificity of the 5-gene risk score to predict survival risk of patients
