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.
