Analysis of the immune infiltration landscape and immune checkpoints in HCC patients. (A-B) The distribution of tumour-infiltrating immune cells between the high- and low-risk groups based on the matrix stiffness-related ECM gene signature. (C-D) Comparison of box plots of 13 immune functions in the high- and low-risk groups of HCC patients. (E-P) Comparison of immune checkpoint genes between the high- and low-risk groups. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.001; ns, not significant
