Data shown as: crude mean (standard deviation), except for TC/HDL-C, TG, glucose, t-PA, and PAI-1, shown as: median (interquartile range); BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; TC: total cholesterol; LDL-C: low density lipoprotein cholesterol; HDL-C: high density lipoprotein cholesterol; TG: triglycerides; Glucose: fasting plasma glucose; t-PA—tissue plasminogen activator; PAI-1: plasminogen activator inhibitor
p-value: t-test (allowing for unequal variances) was performed on age-adjusted residuals to evaluate significance of difference between means; TC/HDL, TG, glucose, t-PA, and PAI-1 were first log-transformed.
