Figure 6. Immune infiltration analyses indicating the high immune infiltration status of high-FRLSG patients. (A) Stacked histogram demonstrated 22 different specific immune cells infiltration in each GC patient. (B) boxplot showed the difference of immune cell infiltration between the high- and low-FRLSG patients. *P < 0.05, **P < 0.01, and ***P < 0.001. (C) Heatmap illustrated the estimated scores of immune signatures calculated by ssGSEA and ESTIMATE algorism in the high- and low-FRLSG patients.
