To find out the correlation between the risk scores and tumor-infiltrating immune cells, we utilized seven techniques that are generally accepted to estimate the immune infiltrating cells, including TIMER, XCELL, CIBER-SORT, QUANTISEQ, EPIC, MCPCOUNTER, as well as CIBERSORT-ABS, and found out that the relationship between the tumor-infiltrating immune cells, such as CD4 + T cells, resting mast cells, common lymphoid progenitors, uncharacterized cells, macrophage M0, macrophage M1, and neutrophils and the high-risk group was positive (p < 0.01). This evidence concerns the gene CD4 and neoplasm.
