During colonoscopy	29 (13.3%)	9 (2.3%)	5.86 (2.82–12.1)
During EGD and/or colonoscopy	54 (24.8%)	29 (7.3%)	3.38 (2.22–5.15)
AMs
During EGD	40 (18.3%)	30 (7.6%)	2.42 (1.55–3.78)
During colonoscopy	39 (17.9%)	12 (3.0%)	5.90 (3.16–11.0)
During EGD and/or colonoscopy	61 (28.0%)	37 (9.3%)	2.99 (2.06–4.35)
