IMT = intima-media thickness.

*Odds ratios for 1 standard deviation increments of intima-medial thickness (IMT), diameter, wall area (calculated as described in the methods).

Level of adjustment: Model 1 includes the vascular measure(s) only; Model 2 adds age, race, gender (for the full sample), and height; Model 3 includes age, gender (for the full sample), cigarette years, body mass index, blood pressure medication use, systolic and diastolic blood pressures, LDL- and HDL-cholesterol, white blood count, and cholesterol medication use.
