Results of multiple linear regression of the association between physical activity with disease activity as continuous variables, for CD and UC
| CD (n = 176) | UC (n = 162) | |||
|---|---|---|---|---|
| β-coefficient (95% CI)a | p value | β-coefficient (95% CI)a | p value | |
| Total physical activity score | ||||
| Crude | − 0.406 (− 0.698 to 0.114) | 0.007 | − 0.006 (− 0.015 to 0.003) | 0.162 |
| 1 | − 0.395 (− 0.693 to 0.097) | 0.010 | − 0.005 (− 0.014 to 0.004) | 0.293 |

CD disease activity scores can range from 0 to > 450 and UC disease activity scores can range from 0 to 19

Model 1: adjusted for age (years), gender (m/f), BMI (kg/m2) and education level (low/middle/high)
Model 2: as model 1 plus age at diagnosis (years), medication use (yes/no) and previous IBD-related surgery (yes/no)
