Using multiple linear regression (adjusted for age, sex, education, APOE ε4 status, cognitive scores, BMI, smoking, alcohol intake, and history of hypertension, diabetes mellitus, hyperlipidemia, and coronary heart disease), the researchers found negative associations for plasma p-tau181 with high-moderate dark vegetable consumption (β = −0.719, 95% CI = −1.249, −0.189, p = 0.008) and high-moderate grape consumption (β = −0.545, 95% CI = −0.928, −0.162, p = 0.006) among the participants who had plasma data (n = 138). Here, APOE is linked to coronary artery disorder.
