Adjusted CHD incidence rate for women, men, and overall, by categories of carotid intima-media thickness (CIMT) and presence or absence of plaque. For every CIMT category (i.e., <25th percentile, 25th to 75th percentile, and >75th percentile), for the overall group (green bars), men (yellow bars), or women (orange bars), having carotid artery plaque is associated with a higher incidence of coronary heart disease.
