aNHANES data includes non-pregnant participants ages 40–79 without prior self-reported MI or stroke. Data are weighted using the full sample 2-year mobile exam centre weight.
bNHANES collected information about Asian ethnicity, whereas MESA collected data from Chinese participants specifically.
cFor MESA, diabetes was defined as use of insulin/oral hypoglycaemic agents or fasting glucose ≥126 mg/dL. For NHANES, diabetes status was ascertained by participant's report of diabetes diagnosis from a doctor.
