β represents unstandardized regression coefficients.
Mean ± SD of executive, memory, attention and global domains were −0.01±0.7, −0.01±0.8, 0.02 ±0.8 and −0.02±0.6, respectively.
Model 1: Adjusted for age, sex, race and education.
Model 2: Adjusted for age, sex, race, education, body mass index, smoking status, prevalence of diabetes, total cholesterol and depression measured at Y30 examination.
Abbreviations: SBP: systolic blood pressure and DBP: diastolic blood pressure; SD: standard deviation.
