    LDL-C was measured using ultracentrifugation.

  2. Percent Change From Baseline in Non-High Density Lipoprotein Cholesterol (HDL-C) at Week 12 [ Time Frame: Baseline and Week 12 ]
  3. Percent Change From Baseline in Apolipoprotein B at Week 12 [ Time Frame: Baseline and Week 12 ]
  4. Percent Change From Baseline in the Total Cholesterol/HDL-C Ratio at Week 12 [ Time Frame: Baseline and Week 12 ]
