Receiver operating characteristic (ROC) curve for prediction of the live birth rate using serum progesterone levels on the day of embryo transfer. AUC = area under the curve. The serum progesterone cut-off point (32.5 ng/ml) with 70 % sensitivity and 50 % specificity was significant predictor (AUC = 0.61, 95 % CI: 0.54–0.68, P = 0.002)
