Intestinal permeability after 14 days of FEC60. Decreased intestinal permeability after 14 days of FEC60. Small intestinal permeability was probed by measuring the urinary cumulative 5-hour amount of lactulose (Lactulose% = percentage of ingested lactulose), mannitol (Mannitol% = percentage of ingested mannitol) and the Lactulose to Mannitol ratio. Data are reported as medians and the range and analyzed with Wilcoxon matched-pairs signed rank test.
