Figure 4. Immune landscape of IRG subtypes in the TCGA cohort. (A) Differences in TME scores and infiltration levels of immune cells between the two distinct subgroups. (B) The comparisons of stromal score, immune score, and tumor purity between different subgroups. (C) The Kaplan–Meier survival regarding the stromal score, immune score, and tumor purity in GC patients. (D) The boxplot of the differences of the immune cells infiltration between two distinct subgroups. (E) Relative proportion of immune infiltration in two distinct subgroups. (F) The Kaplan–Meier survival analysis of the correlation between the infiltration levels of the immune cells and OS in GC. *P < 0.05, **P < 0.01, ***P < 0.001.
