ABI: ankle brachial index, SE: standard error.

^aABI at Exam 1 excluding ABI > 1.4.

^bABI = ankle brachial index; SE = standard error

^cAdjusted for age, sex, and leading ancestry informative PCs.

^dPooled analyses adjusted for race/ethnicity using PCs; Interaction tests based on self-reported race/ethnicity.
