Reference category is the AD group. Adjusted returns variable is multiplied by hundred for easier interpretation. aMCI, amnestic Mild Cognitive Impairment; AD, Alzheimer's dementia; B, unstandardized beta co-efficient; S.E, standard error; Exp(B), odds ratio; C.I, confidence interval; L, lower bound; U, upper bound.
