Key result
Repeat postprandial triglyceride testing demonstrates strong reproducibility with ~0.87 correlation, matching fasting lipid reliability.
Why the study?
The reproducibility of markers for postprandial lipemia in an epidemiologic field setting was uncertain.
Are postprandial measurements of triglycerides and retinyl palmitate reliable markers in an epidemiologic field study?

Yes
Are postprandial measurements of triglycerides and retinyl palmitate reliable markers in an epidemiologic field study?
Effect estimate: r = 0.87 for triglycerides; r = 0.94 for retinyl palmitate
Postprandial measurements of 9.0-hour triglycerides and retinyl palmitate levels demonstrate strong reliability, comparable to or exceeding fasting lipid measurements.
Brown et al. (1992) conducted an observational in Postprandial lipemia (n=10). Repeat fat tolerance tests was evaluated on Reproducibility of postprandial triglycerides and retinyl palmitate at 9.0 hours (r = 0.87 for triglycerides; r = 0.94 for retinyl palmitate). Repeat measurements of postprandial triglycerides (r=0.87) and retinyl palmitate (r=0.94) at 9.0 hours demonstrated strong reliability, comparable to fasting lipid measurements.
