Table 3.

Sensitivity (Se) and specificity (Sp) values and area under the curve (AUC), for the amplitudes of early-P3a (e-P3a) and late-P3a (l-P3a).

		AUC	Se	Sp
e-P3a	sdaMCI vs. mdaMCI
	Amplitude Fz	0.72	0.73	0.74
	Amplitude Cz	0.75	0.73	0.74
	Amplitude Pz	0.79	0.91	0.68
l-P3a	sdaMCI vs. mdaMCI
	Amplitude Fz	0.78	0.73	0.79
	Amplitude Cz	0.78	0.64	0.74
	Amplitude Pz	0.82	0.82	0.68
	Control vs. mdaMCI
	Amplitude Fz	0.76	0.73	0.75
	Amplitude Cz	0.77	0.73	0.60
	Amplitude Pz	0.74	0.64	0.70

The highest sensitivity and specificity scores for each type of ROC analysis (for those amplitudes in which the Group factor exerted a main effect) are highlighted in bold type. sdaMCI: single-domain amnestic mild cognitive impairment; mdaMCI: multi-domain amnestic mild cognitive impairment.
