Receiver operating characteristic (ROC) curve used to determine the serum HE4 cut-off value with the Youden index for the TTN detection. The area under the curve (AUC) value for the serum HE4 was 0.75 (95% CI 0.60-0.86); statistic 3.50; +LR 2.22 (95% CI 1.20-4.00); -LR 0.39 (95% CI 0.20-0.79) and ; Youden index .
