(A) E2, P4, T levels and the E2:P4 ratio as diagnostic tests for women with tubal EP were assessed by the receiver operating curve (ROC) test. ROC analysis was performed with SPSS version 16.0 for Windows, and statistical significance (P value) is indicated. The area under the curve was 0.99 (95% CI: 0.98-1.00) for E2, 0.86 (95% CI: 0.75-0.98) for P4, 0.61 (95% CI: 0.42-0.80) for T, and 0.67 (95% CI: 0.51-0.83) for the E2:P4 ratio. (B) VEGF, PIGF, and ADAM12 as diagnostic tests for women with tubal EP were assessed by the ROC test. The area under the curve was 0.94 (95% CI: 0.86-1.00) for VEGF, 0.47 (95% CI: 0.26-0.68) for PIGF, and 0.48 (95% CI: 0.25-0.69) for ADAM12. (C) The E2: VEGF-A and E2: PIGF ratio as diagnostic tests for women with tubal EP were assessed by the ROC test. The area under the curve was 0.99 (95% CI: 0.97-1.00) for the E2: VEGF-A ratio, and 1.00 (95% CI: 1.00-1.00) for the E2: PIGF ratio.
