Validation of the prognostic value of risk signature. (A) Heatmap presents the expression pattern of three hub genes in each sample, where the colors of yellow to blue represented alterations from high expression to low expression. (B) Distribution of multigene signature risk score. (C) The survival status and interval of HCC patients. (D) K-M curve analysis presenting difference of OS between the high-risk and low-risk groups. (E) Areas under the curve (AUCs) of the risk scores for predicting 1–, 2–, and 3-year OS time. (F) Univariate Cox regression analyses of OS. (G) Multivariate Cox regression analyses of OS.
