Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Phase III First Patient In 06-Feb-2007:; Last Patient Last Visit 16-Jul-2008 110 centers worldwide (International, 12 countries) Eligible patients include drug-naïve patients or patients rendered naïve with the appropriate prior washout at moderately high or high risk for coronary heart disease.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patients were randomized to 1 of 5 treatment groups: ezetimibe/simvastatin combination tablet or atorvastatin alone for 6 weeks stratified according to their baseline risk category stratum (high risk patients with atherosclerotic vascular disease or high risk patients without atherosclerotic vascular disease and moderately high risk patients).
