Fig. 1 Cumulative incidence proportions in percentages with associated 95%CIs of post-colonoscopy colorectal cancer1 among patients with2 and without diverticular disease undergoing colonoscopy (treating death and colectomy as competing risks),3 Denmark, 1995–2015. Patients with inflammatory bowel disease, prior colorectal cancer, or total colectomy were excluded. 1Colorectal cancer diagnosed 7–36 months after a negative colonoscopy. Colonoscopies performed during 1995–2012 were included. 2Recorded in the Danish National Patient Registry before or within 90 days after a given colonoscopy. 3Date of colectomy recorded in the Danish National Patient Registry plus 90 days to avoid ambiguities in coding of dates.
