In addition, high XDH mRNA expression was also correlated with better OS in bladder carcinoma (HR 0.69, 95% CI 0.52 to 0.93, P = 0.015) (Fig. 2E, F) and ovarian cancer (HR 0.87, 95% CI 0.76 to 0.99, P = 0.031) (Fig. 2M, N) and better RFS in breast cancers (HR 0.77, 95% CI 0.69 to 0.86, P = 1.7e−6, Fig. 2G, H). The gene discussed is XDH; the disease is ovarian cancer.
