Absolute hippocampal areas in the optimal slice on the left and right are in mm2. Absolute hippocampal volumes on the left and right are in mm3. Normalized hippocampal areas of the optimal slice to the brain area at anterior commissure on the left and right and normalized hippocampal volumes to total intracranial volume (TIV) on the left and right are in percentages. All values are expressed as ; SE means standard error of AUC (ROC).
