Construction of a nomogram and independent prognostic analysis of risk score. (A) ROC curves for 1-, 3-, and 5-year in the training cohort (left) and test cohort (right). (B) Heatmap of the correlation between clinical features (TNM, stage, grade, gender, age) and risk score (*p < 0.05, **p < 0.01, ***p < 0.001). (C) Nomogram comprised of risk score and clinical traits (TNM, stage, grade, gender, age). (D) Calibration plots of nomogram. (E) ROC curves based on clinical traits and risk score in the training cohort (left) and test cohort (right). (F) Univariate analysis of risk score as an independent prognostic factor in patients with HCC in the training cohort (left) and test cohort (right). (G) Multivariate analysis of risk score as an independent prognostic factor for HCC patients in the training cohort (left) and test cohort (right)
