BMI indicates body mass index; M (SD), mean (standard deviation); MI, myocardial infarction; MR, magnetic resonance imaging.

a

Logistic models to compare the overall difference between the groups adjusted for age and sex.

b

Adjusted for antihypertensive medications.

c

Adjusted for cholesterol.

d

Exercise: 1=never, 2=rarely, 3=occasionally, 4=moderate, 5=high.

e

Model not corrected because age and sex are included in risk score.
