| Index | Sensitivity | Specificity | AUC | 95% CI | Z | P |
|---|---|---|---|---|---|---|
| CART model | 0.979 | 0.896 | 0.949 | 0.914-0.985 | - | - |

| CA125 | 0.393 | 1.000 | 0.725 | 0.658-0.793 | 7.828 | <0.001 |
| CA19-9 | 0.971 | 0.284 | 0.605 | 0.520-0.689 | 8.963 | <0.001 |
| HE4 | 0.750 | 0.761 | 0.797 | 0.739-0.856 | 6.536 | <0.001 |
| VEGF | 0.821 | 0.627 | 0.791 | 0.727-0.856 | 6.177 | <0.001 |
| D-dimer | 0.550 | 0.821 | 0.701 | 0.631-0.771 | 7.991 | <0.001 |
| N | 0.564 | 0.776 | 0.706 | 0.634-0.777 | 7.762 | <0.001 |
Note: The P value in the table is the AUC value of each index compared with the AUC value of the CART model. CART: classification and regression tree.
