Values are means (SD). *Tertiles are based on a reference population of healthy subjects. A low tertile score indicates a small hippocampal or parahippocampal gyrus volume, or an high MTA score; †one patient with missing data; ‡two patients with missing data; §three patients with missing data; ¶four patients with missing data; **five patients with missing data. | ||||
