  1. a BMI body mass index, SD standard deviation, aMCI amnestic mild cognitive impairment, naMCI non-amnestic mild cognitive impairment
  2. b Difference of three continuous variables was determined by one-way variance analysis (ANOVA) with Duncan’s post hoc test. Difference of categorical variables was determined using chi-square test. If a P value < 0.05, it was considered significant. * Compared with control, P < 0.05; # Compared with naMCI, P < 0.05
