A The heatmap of the correlation between risk score and tumor-infiltrating immune cells. B Differences in the expression of the immune checkpoints between the two risk groups. C Differences in TMB of HCC patients in the two risk groups. D Differences in TIDE score of HCC patients in the two risk groups. E The KM curves for the patients with high- and low-TMB. F The KM curves for patients with high TMB + high-risk score, high TMB + low-risk score, low TMB + high-risk score, and low TMB + low-risk score. G Differences in TSI of HCC patients in the two risk groups. H Visualization of gene mutations in low-risk groups. I Visualization of gene mutations in high-risk groups. J The forest plot for the significantly different mutations between the two risk groups. TMB tumor mutational burden, KM curves Kaplan–Meier curves, TSI tumor stemness indices, HCC hepatocellular carcinoma. * P < 0.05, ** P < 0.01, *** P < 0.001
