The results of Kaplan–Meier prognostic analysis showed that high expression of the risk-associated genes (B3GAT2, CD3EAP, FRMPD3, LINC01224, LINC02068, LY6H, and NR6A1) is related to poor prognosis in endometrial cancer patients (P < 0.05, Supplementary Figure 1). Here, NR6A1 is linked to endometrial cancer.
