Subgroup analysis of patients with UC according to whether they demonstrated slower or faster whole gut transit times (WGTT) when consuming high-resistant starch and wheat bran (RS/WB) compared with low RS/WB
| Effect of high RS/WB on WGTT | n | Low RS/WB WGTT (h) | High RS/WB WGTT (h) | NSP usage | |
|---|---|---|---|---|---|
| Low RS/WB | High RS/WB | ||||
| Slowed by 31 (20 to 43)% | 12 | 32 (26 to 38) | 44 (33 to 51) | 45 (31 to 59) % | 61 (46 to 76)% |
| Faster by 36 (12 to 60)% | 7 | 52 (37–67) | 35 (26 to 44) | 77 (70 to 84)% | 77 (56 to 97)% |
| p Value (t test) | 0.0036 | ns | 0.0043 | ns | |
Results are shown as mean and 95% CIs. No statistical difference was found between the two dietary arms for non-starch polysaccharide (NSP) usage in either group.
