The result revealed that the risk score was significantly negatively correlated with CD8+ T cells, plasma B cells, CD4+ T cells, and T cells (|cor| > 0.2, P < 0.001), while it was positively correlated with macrophages, cancer associated fibroblasts, and M0 macrophages endothelial cells (|cor| > 0.2, P < 0.001). Here, CD4 is linked to cancer.
