FIG. 1.
Least squares means in common carotid artery IMT based on linear mixed model adjusted for age, sex, study cohort, IMT reader, image device, and mean baseline IMT value of 0.614 mm. A significant separation in mean IMT between treatment groups (intensive, ■; conventional, ▲) emerged between years 1 and 6 (P < 0.0001) that persisted to year 12 (P = 0.048). From years 6 to 12, the progression rates are similar for the two treatment groups.
