Figure 4. The correlation between IL18RAP expression and immune checkpoint genes, TMB, MSI in pan-cancer. (A) Excluding KICH, the expression of IL18RAP was closely correlated with immune checkpoint genes in 32 cancers except KICH. (B) The analysis's findings on the relationship between TMB and IL18RAP mRNA level. (C) The analysis's findings on the relationship between MSI and IL18RAP mRNA level. *p < 0.05 and **p < 0.01.
