Immunological classification of hepatitis B virus-positive hepatocellular carcinoma by transcriptome analysis

Figure 2 Comparisons of immune features between the immune-specific subtypes of hepatitis B virus + hepatocellular carcinoma. A: Imm-H shows significantly higher expression levels of HLA genes; B: Immune scores; C: PD-L1 expression levels; D: Ratios of immunostimulatory to immunosuppressive signatures (CD8+/CD4+ regulatory T cells) than Imm-L. The two-tailed Student’s t test P values are shown in (A, C, D), and the one-tailed Mann–Whitney U test P values are shown in (B).
