Figure 9. Correlation analysis between risk score and immune cell infiltration. (A) The number of immune cell infiltration in patients with low-risk and high-risk group. (B) Heatmap to visualize the relative abundance of 28 infiltrating immune cell populations in the samples of HCC patients after risk score ordered for low to high. (C–H) The ggscatterstats plots of the significant correlation between risk score and different immune cells infiltration status.
