Furthermore, we used various algorithms to investigate the relationship between risk score and the quantitative value of immune infiltration, we selected P value<0.001 to study further, the results obtained from the preliminary analysis are shown in Figure 5(f), more immune-suppressive cells such as cancer-associated fibroblast, M2 macrophage, Treg cell, T follicular helper cells, and T cell CD4+ Th2 are positively related to the risk score on different platforms, whereas NK cell activated cell, Monocyte, and CD4+ Th1 cells are neglective related to the risk score. This evidence concerns the gene CD4 and cancer.
