- Data are given as median (25–75 percentiles). Mann-Whitney U-test (between group comparisons); Wilcoxon Signed Rank Test (within group comparison of changes). * Statistically significant p < 0.05: a RYGB vs. VSG; b Changes pre-to post-surgery within group (RYGB); c Changes pre-to post-surgery within group (VSG); d between-group comparisons (RYGB vs. VSG) of the changes pre-to post-surgery. GSRS-IBS: Gastrointestinal Symptom Rating Scale-Irritable Bowel Syndrome (range 1–7: Increasing values indicates increasing symptoms). FTS: Food Tolerance Score (range 1–27: Increasing values indicates better tolerance)
