CD4 and cancer: The risk score showed positive correlation with B cell (p = 0.669) (Figure S5A), NK cells (P = 0.313) (Figure S5D), cancer-associated fibroblasts (p = 5.974E−07) (Figure S5E), endothelial cells (p = 0.025) (Figure S5F) and macrophages (p = 8.517E−05) (Figure S5G), while CD4 + T cells (p = 0.074) (Figure S5B), CD8 + T cells (p = 0.327) (Figure S5C) and uncharacterized cells (p = 6.363e−08) (Figure S5H) were all negatively associated with the risk score.
