Linear regression models for associations between very long-chain saturated fatty acids (VLSFAs) and four tests of cognitive function (n = 806). AFT, Animal Fluency Test; CERAD, Consortium to Establish a Registry for Alzheimer’s Disease; CERAD-IR, CERAD immediate recall; CERAD-DR, CERAD delayed recall; DSST, Digit Symbol Substitution Test; VLSFAs, very long-chain saturated fatty acids. Model 1, did not adjust for any confounders. Model 2, adjusted for age, sex, race, education, and PIR. Model3, adjusted for age, sex, race, education, PIR, BMI, waist circumference, alcohol intake, smoking status, hypertension, diabetes mellitus, stroke and coronary heart disease, depression score
