Outcomes
Primary Outcome Measures
High-density Lipoprotein Cholesterol (HDL-C) Concentration at Baseline
Blood level of HDL-C was measured following a 12-hours fasting.
High-density Lipoprotein Cholesterol (HDL-C) Concentration at Week 6
Blood level of HDL-C was measured following a 12-hours fasting.
Cholesterol Ester Production Rate at Baseline
Cholesterol ester production rate was calculated using a 3-pool model with a simulation, analysis and modeling (SAAM II) program.
Cholesterol Ester Production Rate at Week 6
Cholesterol ester production rate was calculated using a 3-pool model with a simulation, analysis and modeling (SAAM II) program.
Secondary Outcome Measures
Low-density Lipoprotein Cholesterol (LDL-C) and Total Cholesterol Concentration
Blood level of LDL-C and total cholesterol (TC) was measured following a 12-hours fasting.
Cholesterol Ester Fractional Catabolic Rate
Cholesterol ester fractional catabolic rate were calculated using a 3-pool model with a simulation, analysis and modeling (SAAM II) program. Fractional catabolic rate was the percentage of cholesterol ester which was replaced, transferred or lost per unit of time.
Low-density Lipoprotein Associated With Apolipoprotein B (LDL-apoB) Production Rate
LDL-apoB production rate were calculated using a 3-pool model with a simulation, analysis and modeling (SAAM II) program.
Low-density Lipoprotein Associated With Apolipoprotein B (LDL-apoB) Fractional Catabolic Rate
Fractional catabolic rate for LDL ApoB were calculated using the 13 carbon (13C) isotopic enrichment of very low density lipoprotein (VLDL) as the limiting value. Isotope 13C in plasma was measured using Gas Chromatography-Combustion-Isotope Ratio Mass Spectrometry (GC-C-IRMS).
High-density Lipoprotein Associated With Apolipoprotein A1 (HDL-apoA1) Production Rate
HDL-apoA1 production rate were calculated using a 3-pool model with a simulation, analysis and modeling (SAAM II) program.
High-density Lipoprotein Associated With Apolipoprotein A1 (HDL-apoA1) Fractional Catabolic Rate
Fractional catabolic rate for HDL-apoA1 were calculated using the 13C isotopic enrichment of VLDL as the limiting value. Isotope 13C in plasma was measured using GC-C-IRMS.
Cholesterol Efflux Rate
Cholesterol efflux rate was measured using isotope dilution method in which rate of appearance of isotope 13C-free cholesterol in plasma representing whole body efflux from tissues was assessed. Isotope 13C in plasma was measured using GC-C-IRMS.
