Informs sample size planning for VLDL kinetic studies; extends methodological standards for stable isotope tracer research.
Observational (n=8)
Stable isotope-labeled tracer measures of VLDL kinetics show 15-25% intraindividual variability, indicating that sample sizes of 6-10 for paired and 12-20 for cross-sectional studies are needed to detect 25-30% differences.
Magkos et al. (2007) conducted an observational in Healthy (n=8). Stable isotope-labeled tracer techniques was evaluated on Repeatability of plasma FFA, VLDL-TG, and VLDL-apoB-100 kinetics. Stable isotope-labeled tracer measures of plasma FFA, VLDL-TG, and VLDL-apoB-100 kinetics demonstrated intraindividual day-to-day variability ranging from 15% to 25%.
