Measuring Effects on Intima Media Thickness: An Evaluation of Rosuvastatin Ongoing Trial. A trial that evaluated the effect of rosuvastatin on carotid intima-media thickness in asymptomatic patients with a low risk of coronary heart disease events
Conclusion The change in maximum carotid intima-media thickness for the 12 carotid artery sites was -0.0014 mm/year for the rosuvastatin group vs. +0.0131 mm/year for the placebo group (p < 0.001). Similar results were observed for segment-specific rates, except for the change in the internal carotid artery, which was p = 0.02
