  1. Optimal cutoffs were determined via Youden Index. Youden Index, J = Sensitivity + Specificity − 1, good (J > 0.5), moderate (0.3 < J > 0.5), or poor (J < 0.3) discriminative ability. AUC = Area under the Curve; CI = Confidence Interval; DA = divided attention; MoCA = Montreal Cognitive Assessment; SA = sustained attention; TMT = Trail-Making-Test.
