Participant Flow

This study enrolled adults 18 - 75 years with fasting low-density lipoprotein cholesterol (LDL-C) ≥ 100 mg/dL and \< 190 mg/dL, fasting triglycerides ≤ 400 mg/dL and a National Cholesterol Education Program Adult Treatment Panel III Framingham risk score of 10% or less. First patient enrolled 06 July 2011, last patient enrolled 25 November 2011.

Participants were randomized with equal allocation into 1 of 9 treatment groups. Randomization was stratified on the basis of screening LDL-C concentration (\< 130 mg/dL \[3.4 mmol/L\] or ≥ 130 mg/dL).
