The impact of diabetes on cancer detection during the prevalence round of a national screening program for colorectal cancer
Authors' conclusion
Despite a lower participation rate, the effect of CRC screening was higher in individuals with diabetes.
Study context

- Exposure
- Invited vs not yet invited to CRC screening, in individuals with and without diabetes
