Instruments	AUC	P	95% CI	Sensitivity (%)	Specificity (%)	Cutoff point
CAMCOG	0.975	< 0.0001	94-99	95	93	75 points
MMSE	0.972	< 0.0001	93-99	93	93	23 points
Constructive praxis	0.905	< 0.0001	85-95	69	98	4 points
Total praxis	0.858	< 0.0001	79-90	73	84	9 points
Ideomotor praxis	0.568	0.111	49-65	66	44	4 points

AUC = area under the curve; CI = confidence interval; CAMCOG = Cambridge Cognitive Examination; MMSE = Mini-Mental State Examination. P from chi-square test.
