bThe models were adjusted for age, sex, and education.
cThe white matter hyperintensity volume was the percentage over the total cerebral cranial volume above the tentorium and was log transformed.
dThe large white matter hyperintensity volume was defined as that more than one standard deviation higher than the age-specific mean value.
eBonferroni correction was used to adjust for multiple testing, and significant associations were claimed if P<.05/18 (2.8×10−3), where 18 is the number of tests performed.
