Predicted means of cognitive outcomes and BMI in tertiles at baseline and 1-year follow up for mild cognitive impairment participants. The predicted means of cognitive outcomes are presented for tertiles of BMI adjusted for age, education, and sex. Lower scores represent worse performance for the global composite score and Mini-Mental Status Examination (MMSE), whereas higher scores represent decline in clinical dementia rating (CDR) sum of boxes and Alzheimer Disease Assessment Scale-Cognitive subscale. Less cognitive decline over 1-year is apparent in the highest BMI tertile across the measures. BMI indicates body mass index.
