MTA score at baseline*
Highest tertileMiddle tertileLowest tertilep Value trend analysis
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.
MMSE, Mini mental state examination; AD, Alzheimer type dementia; CD, cognitive decline: patients with Alzheimer type dementia at follow up or patients with severe cognitive decline at follow up without dementia.
