Classification of CIND patients and healthy controls

Measures	Sensitivity	Specificity	Overall	ROC	p Value*
Hippocampal volume	0.38	0.87	0.77	0.78	0.02
+ MTL NAA	0.40	0.87	0.76	0.84	0.03
+ Neocortical gray matter	0.38	0.87	0.77	0.79	0.15

Values are mean ± SD. Sensitivity, specificity, and overall correct classification were calculated using logistic regression analysis in 24 controls and 17 CIND patients.

^*Analysis by logistic regression.

CIND = cognitively impaired but nondemented; ROC = receiver operator characteristic area under the curve; MTL NAA = medial temporal lobe N-acetylaspartate.
