- NOTE: Mixed models with repeated measurements of natural log transformed serum adipokine concentrations were used.
- Overall estimates are averages across the two diets. Estimates for leptin assume a quadratic trend in time. All other estimates assume a linear trend in time. Data presented correspond to geometric means and 95% CIs. No difference in trend by diet was observed for any biomarker.
- aSignificant quadratic trend was observed for serum leptin (P = 0.01); no difference observed between baseline and Week 52 serum leptin concentrations (P > 0.05).
- bAverage trend in time across diets was borderline significant for serum A/L ratio (P = 0.05).
