In addition, the risk score was positively correlated with tumor-related pathways such as EGFR (R = 0.57), hypoxia (R = 0.56), MAPK (R = 0.56), and TGF-β (R = 0.38) (Figure 6F), and immunosuppressive features such as angiogenesis (R = 0.33), CAFs (R = 0.50), and TAMs (R = 0.55) (Supplementary Figure S5), which was similar to the previous results (Figure 3F). Here, EGFR is linked to neoplasm.
