Pearson’s correlation analysis, the expression changes, and IPS analysis between three immune checkpoint genes and the risk score. A Pearson’s correlation analysis between the CTLA4, PD1, and PD-L1 expression and the risk score; B boxplots of three immune checkpoint genes expression in the high- and low-risk groups stratified by the risk score; C IPS comparison between high-risk and low-risk groups in patients with EC in four types. PD-1_pos or CTLA4_pos indicated anti- PD-1 or anti-CTLA4 therapy, respectively
