PRIMARY outcome

Timeframe: baseline to 6 weeks

Population: The analysis was performed on the intent to treat (ITT) population. Although 248 subjects received randomized treatment, two of the subjects did not have at least one baseline and at least one postbaseline lipid determination and thus could not be analyzed in the ITT population. Therefore, the actual ITT population consisted of 246 subjects.

Least squares mean percent change from Baseline in LDL-C at the end of Step 1 (Week 6) in the pooled groups who received ezetimibe plus simvastatin compared with pooled groups who received simvastatin monotherapy
