Find the cutoff for your test: AUC with 95% CI (Hanley & McNeil), optimal threshold by Youden’s index, sensitivity, specificity and a PNG curve.
If you use it in your thesis or in a paper, cite it so that readers of your Methods section know how the calculation was done.

For your Methods section: Discriminative ability was assessed with the area under the ROC curve (Hanley & McNeil, 1982) and the cut-off point was chosen with the Youden (1950) index, using the Ciudad Science ROC curve calculator (Ciudad-Fernández, 2026).
