The correlations between immune checkpoint and risk score

(A) The boxplot shows the expression of immune checkpoints in high- and low-risk groups. (B) The correlations between immune checkpoints are shown. (C–E) The relationships between CTLA4 (C), HAVCR2 (D), and PDCD1 (E) and the risk score are shown. (F) The expression difference of PD1 between high-and low-risk groups. (G–J) The differences of IPS (G), IPS_ ctla4 (H), IPS_ ctla4_ pdl1_ pd1_ pdl2 (I), and IPS _ pdl1_ pd1_ pdL2 (J) in patients with different risk are shown. ∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001. ns, not significant.
