Each model (A-E) is a separate linear regression model adjusted for age at death, sex, APOE4, education, total energy intake, and late-life cognitive activities and global AD pathology (not shown). Model F is a linear mixed-effect model adjusted for age at death, sex, APOE4, education, total energy intake, and late-life cognitive activities (not shown), and their interactions with time (years before death).
Estimates are reported for the interaction of predictor with time. β-estimate for MIND diet score is for 1 standard deviation (SD=1.42) increase.
Model A excludes individuals with mild cognitive impairment or other conditions contributing to cognitive impairment at the baseline.
Model B MIND diet score is based on dietary information collected at the baseline.
Model C restrict analysis on participants whose MIND diet scores were relatively constant (e.g., consecutive change less than 20%) during the study period.
Model D is further adjusted for physical activity
Model E includes cases diagnosed with postmortem diagnosis of Alzheimer’s disease based on NIA-Reagan consensus recommendations.
Model F evaluates the rates of cognitive decline. β-estimate indicates rate of change in cognitive decline per year.
