Due to the variability of triglycerides, a 10% allowance existed in the initial protocol, which permitted patients to be enrolled with qualifying triglycerides ≥135 mg/dL. Protocol amendment 1 (May 2013) changed the lower limit of acceptable triglycerides from 150 mg/dL to 200 mg/dL, with no variability allowance. Median trial follow-up duration was 4.9 years (minimum 0.0, maximum 6.2 years). Statin stabilization Medication washout Lipid qualification
