Healthy: both non-hypertensive and non-diabetic. Data are presented as mean ± SD or n (%). aP-value is the difference between the healthy and hypertensive group and bP-value is the difference between the healthy and diabetic group. P-values for mean concentrations are derived from independent sample t-test and P-values for prevalence (%) are obtained from the chi-square test. Elevated TG: TG ≥ 150 mg/dL; Elevated TC: TC ≥ 200 mg/dL; Elevated LDL: LDL ≥ 130 mg/dL and Low HDL: HDL < 40 mg/dL in men and < 50 in women; (National Cholesterol Education Program, ATP III, 2001)
