Results showed that the expression of WFDC1 (P = 0.0016, hazard ratio (HR) = 0.66 (0.51–0.86)) and IL-17D (P = 0.019, HR = 0.7(0.52–0.95)) was positively correlated with overall survival of ovarian cancer patients in TCGA dataset (Fig. 4c). The gene discussed is WFDC1; the disease is ovarian cancer.
