SLC7A11 and ovarian cancer: Kaplan–Meier survival curves (Figure 2A) showed that patients with ovarian cancer with a high SLC7A11 expression had significantly poorer PFS (p < 0.001) and OS (p < 0.001) than patients with a low expression of SLC7A11, which was confirmed by our univariate Cox (Table S8) and multivariate Cox proportional hazards regression analyses (hazard ratio [HR] = 2.351, 95% CI 1.510–3.659 for PFS, Table S9; HR 2.851, 95% CI 1.658–4.902 for OS, Table S10).
