SI conversion factor: To convert cholesterol to millimoles per liter, multiply by 0.0259.
a
P values are from linear (continuous variables) and logistic (categorical variables) regression models and are adjusted for age at baseline.
b
Calculated as weight in kilograms divided by height in meters squared.
c
APOE ε4 allele positive is defined as having at least 1 copy of the ε4 allele.
