(a) Forest map of the 4-gene prognostic model established by multivariate Cox risk regression analysis; (b) Kaplan-Meier OS curves for the high- and low-risk groups are plotted based on risk score. Horizontal axis: survival time; vertical axis: overall rate; red line: high-risk samples; blue line: low-risk samples. (c) ROC curves based on the risk model.
