Immune infiltration analysis between HBV and HBV-HCC. (A) Stacked histogram of the infiltration ratio of 22 immune cells between HBV and HBV-HCC in each sample. (B) Heat map of correlation between 22 immune cells, red indicates positive correlation, blue indicates negative correlation, and the values in the heat map are the magnitude of correlation between the corresponding immune cells. (C) Box plot of the difference in infiltration of 22 immune cells between HBV and HBV-HCC. (D) Box-line plot of the difference in expression of 12 immune functions between HBV and HBV-HCC. *p < 0.05, **p < 0.01, ***p < 0.001.
