Total hippocampus	0.72	31.5	0.70/0.68	0.35	0.75	28.7	0.61/0.75	0.98

% MC, percentage of subjects misclassified; Sens/Spec, sensitivity/specificity, AUC, area under the curve of the receiver operating characteristic graphic (ROC); Power, power to the detect a difference between subjects diagnosed with MCI and controls (MCI), respectively, AD and controls (AD) at the significance level alpha = 0.05.

Please see text for ROC and sensitivity/specificity of CA1 in combination with CA1‐2 transition to discriminate between AD and controls.
