  1. Kaplan-Meier analysis. Clustered P values were calculated using Cox proportional hazard model with cohort as independent variable. Study population is the elevated-TG cohort (TG ≥150 mg/dL) and high-TG subcohort and their propensity score matched comparators with TG < 150 mg/dL and HDL-C > 40 mg/dL
  2. HDL-C high-density lipoprotein cholesterol, TG triglycerides
