CD8A and neoplasm: To compare the differences of infiltrating immune cells between the high-risk and low-risk groups, we constructed a violin plot showing that the proportions of tumor-infiltrating CD8+ T cell, activated NK cell and M1 macrophages in high-risk group were significantly lower than those in low-risk group, while the proportion of tumor-infiltrating M2 macrophages in high-risk group was much higher than that in low-risk group (Figure 9D).
