Rates of changes in global cognitive scores over time as a function of MedDiet score tertiles (left), MedDiet wine score tertiles (middle), and Healthy Eating Index–2005 (HEI-2005) score tertiles (right). The first tertile is represented by dashed lines, the second by solid plus dashed lines, and the third by solid lines. Rates of change among Chicago Health and Aging Project (CHAP) participants were significantly associated with those whose MedDiet scores were in the highest or third tertile (solid lines; β = −0.0171, SEE = 0.0046, P = 0.0002) but not with those whose scores were in the second tertile (β = −0.0079, SEE = 0.0045, P = 0.075). Similarly, those whose MedDiet wine scores were in the third tertile experienced significantly slower rates of cognitive decline (β = −0.0106, SEE = 0.0046, P = 0.021) but not those whose scores were in the second tertile (β = −0.0063, SEE = 0.0045, P = 0.156). There were no significant associations in rates of change in cognitive scores between CHAP persons categorized by HEI-2005 tertiles (for the third tertile: β = −0.0171, SEE =0.0046, P = 0.0002; for the second tertile: β = −0.0021, SEE = 0.0042, P = 0.621).
