Table 6.

Diagnostic value of dCDT parameters and CERAD total scores in differentiating healthy individuals (HC) and patients with amnestic mild cognitive impairment (aMCI).

	HC vs. aMCI			HC vs. aMCI with normal CDT scores
	Sensitivity	Specificity	Accuracy	Sensitivity	Specificity	Accuracy
dCDT	85.4^a	77.5^a	81.5^a	81.8^b	72.6^b	78.0^b
CERAD total score	84.6^c	70.3^c	77.5^c	84.5^d	69.8^d	76.0^d

HC: healthy control individuals; aMCI: amnestic mild cognitive impairment; dCDT: digital Clock Drawing Test; dCDT variables in the regression model: ^aCDT score, time in air, and time not painting; ^btime in air; CERAD = Consortium to Establish a Registry for Alzheimer’s Disease neuropsychological battery. ^c,dCERAD total score cut-off 80.0 points.
