These results demonstrated that a high expression of SUCNR1 was associated with poor PFS (p = 0.0073, HR = 1.49, 95% CI = 1.11–2), but not with OS (p = 0.34, HR = 1.21, 95% CI = 0.82–1.79), in ovarian cancer patients (GSE9891, Figure 6D and Supplementary Figure S5D). Here, SUCNR1 is linked to ovarian cancer.
