*OR of being tested withFOBT or colonoscopy versus no test for each calendar year. Results from multivariate adjusted logistic regression model adjusted for gender, age, PCGs, managed care model, Year considered, Canton Uri vs the other neighboring cantons. Interaction term added testing the interaction between period before the organized screening program (years 2011–2012 vs 2015.2018) and canton Uri vs the other cantons. Years 2013 and 2014 excluded given the lack of information about which specific insuree had had FOBT that was directly reimbursed, by Canton Uri and for which no bill was sent to health insurance.
