^*standardized values: units of 21.5 mmHg for systolic pressure, 35.6 mg/dL for total cholesterol, 14.8 mg/dL for HDL cholesterol. 0.19 mm for near wall intima media thickness, 0.21 mm for far wall intima media thickness, and 0.18 mm for mean of near and far wall intima media thickness

^†All variables are significantly associated with coronary heart disease outcomes except for the near wall intima media thickness.
