  1. §Odds ratios (OR) or hazards ratio (HR) associated with an increment of 1 standard deviation of the vascular measure in the logistic and Cox proportional hazards models respectively
  2. †Plaques or shadowing at any right or left carotid site (internal, CCA, or bifurcation)
  3. ‡Models 2 and 3 are demographic and risk factor adjusted models respectively. The covariates for prevalent disease are found in Table 2 and those for incident events are listed in Table 3 for women and Table 4 for men.
  4. CHD, coronary heart disease that includes coronary artery procedures.
