Colonic and whole gut permeability in vivo comparing young adults vs. elderly. (A) 5–24 urinary sucralose/erythritol ratio in healthy individuals. (B) 5–24 urinary sucralose/erythritol ratio in IBS patients. (C) 0–24 urinary sucralose/erythritol ratio in healthy individuals. (D) 0–24 urinary sucralose/erythritol ratio in IBS patients. Values are presented in scatter plots with median line and IQR (25–75th interquartile range). Urinary sugar ratios were compared between age groups with the use of Mann-Whitney U-tests.
