| Invited | Attended | Unadjusted uptake(%) | Adjusted odds ratio*(95% confidence interval) | |
|---|---|---|---|---|
| *The adjusted model included the following variables: socioeconomic deprivation, travel distance, urban-rural status, screening location, and type of screening facility. Distance was examined as a categorical variable or as a continuous variable in separate models. | ||||
