Data are presented as mean (SD) and mean difference (95% CI) or median (IQR) and fold-change (95% CI).
Statistical analyses were performed using linear mixed effects models with treatment (diet) and period as fixed effects and subject as random effect.
Abbreviations: CI, confidence interval; IQR, interquartile range; SD, standard deviation.
This is a confirmatory finding according to the pre-defined testing procedure (see Statistical Analysis Plan, eMethods3, for details).
Fold change between groups is presented.
