Results from the mixed model analysis of individual rectal motor complex parameters in control subjects (CS) and in those with rectal hypersensitivity (RH) and normal rectal sensation (NS)
| Difference | Percentage change in geometric mean (95% CI) |
|
|---|---|---|
| Amplitude | Periodicity | |
| Day (CS−RH) | 7 (−1 to 14) | 93 (76 to 111)*** |
| Day (CS−NS) | −3 (−14 to 10) | 15 (3 to 29)* |
| Day (RH−NS) | −8 (−15 to −1)* | −40 (−46 to −35)*** |
| Night (CS−RH) | −9 (−15 to −2)* | 40 (28 to 53)*** |
| Night (CS−NS) | −12 (−22 to −1)* | 9 (−2 to 21) |
| Night (RH−NS) | −4 (−11 to 4) | −22 (−29 to −15)*** |
| CS (day v night) | 4 (−3 to 11) | 23 (10 to 37)*** |
| RH (day v night) | −11 (−15 to −7)*** | −11 (−17 to −5)** |
| NS (day v night) | −7 (−13 to 0) | 16 (4 to 30)*** |
Significant interaction effects between group and time was found.
