CI Confidence interval, 4MT Four Mountains Test, EWG Eatwell Guide score, FRS Framingham Risk Score. 4MT score fully adjusted model includes age, sex, education, APOEε4, parental history of dementia, NART score, physical activity score and socioeconomic status as covariates. Self-reported healthy eating score includes age, sex, education, APOEε4, parental history of dementia, APOEε4, physical activity score and socioeconomic status as covariates.
