Reasons given for colorectal cancer (CRC) screening tests at follow-up across four CRC risk strata. Fecal occult blood test (FOBT; a-c) and endoscopy (d-f) Participants were stratified into four strata of risk nested within different screening patterns, and reasons for screening were reported at follow-up. Options provided included: regular check-up or age, family history of colorectal cancer, and physical problem which included signs of a possible problem or follow-up of previous problem. Participants could select more than one option, but were assigned a primary category based on a priority hierarchy: physical problem, family history and regular check-up or age. Figures a & d – Regular screeners; Figures b & e – Episodic screeners; Figures c & f – New screeners. Values on bars are the proportion of participants within each stratum
