Figure 4.Expression levels of important checkpoint molecules including PD-1 (A), PD-L1 (B), CTLA-4 (C), IDO1 (D), and LAG3 (E) were all significantly higher in the high VEGF score subtype. Significantly lower TMB (F), SNV neoantigen number (G), and indel neoantigen number (H) were observed in the high VEGF score subtype.
