WFDC2 and ovarian cancer: All six miRNAs and the tested proteins were significantly associated with the risk of ovarian cancer in the univariate logistic regression analysis (miR-10b-5p: Odds Ratio [OR] = 1.5 [CI95% 1.0–2.4]; miR-21-5p: OR = 2.6 [CI95% 1.7–4.0]; miR-29c-3p: OR = 2.6 [CI95% 1.6–4.2]; miR-141-3p: OR = 1.7 [CI95% 1.3–2.3]; miR-222-3p: OR = 3.9 [CI95% 2.0–7.7]; miR-320b: OR = 15.1 [CI95% 5.8–39.4]; HE4: OR = 10.9 [CI95% 4.3–27.2]; CA-125: OR = 4.7 [CI95% 2.3–9.5].
