Table 3. Urinary sugar excretions (μmol) and ratios of the synbiotic group (n = 10) at baseline and after two weeks synbiotic supplementation, without and with indomethacin challenge.

Values are presented as median and IQR (25-75^th interquartile range). Urinary sugar excretions and ratios at baseline vs. end were compared with the use of a Wilcoxon signed-rank test. L/R, lactulose/rhamnose; S/E, sucralose/erythritol.
