When the annexin V apoptotic index cutoff value was selected as 27.65%, the sensitivity was calculated as 90.0% and the specificity as 93.3% for predicting serous ovarian carcinoma (AUC 0.872, p <0.001, 95% CI 0.761–0.984, Figure 4). The gene discussed is ANXA5; the disease is ovarian serous carcinoma.
