Table 4.
Fecal levels of individual and total short-chained fatty acids in the normal sleep (NS) and partial sleep deprivation (PSD) condition, at baseline and after two days of each intervention (d2). Statistical trends (0.10 > P > 0.05; two-sided values) in the ANOVA are indicated in italic bold. Values shown as µmol/g Dry mass (DM) and as means ± S.E.M.
