EASE TrialEASE Trial•A large proportion of patients in the trial had diabetes (38.4%) and metabolic syndrome by NCEP ATP III criteria (60%).

•Baseline LDL levels were 129 mg/dl in the overall population, 123 mg/dl in the coronary heart disease (CHD) or CHD risk equivalent group, 147 mg/dl in the multiple risk factors group, and 167 mg/dl in the <2 risk factors group.

•The ezetimibe arm had a larger reduction in triglycerides and a larger increase in high-density lipoprotein (HDL) levels.

•The follow-up LDL level in the ezetimibe arm was 95 mg/dl.

•A larger percentage of patients in the ezetimibe arm reached target LDL goals.

•Results were similar across the different statin brands and by the prespecified subgroups of age group, gender, and diabetes status.

•There were no increases in the frequency of alanine aminotransferase (ALT) ≥3 times upper limit of normal (ULN) (0.4% for ezetimibe vs. 0.2% for placebo), aspartate aminotransferase (AST) ≥3 times ULN (0.2% vs. 0.1%), or creatine kinase (CK) ≥10 times ULN (0 in both groups).
