Figure 2 Percentage of colonoscopies stratified into risk groups as defined by the 2020 United States Multisociety Task Force polypectomy guidelines. Tier 1 was defined as no adenomas. Tier 2 was defined as 1-2 adenomas whose size were < 10 mm. Tier 3 was defined as 3-4 adenomas whose size were < 10 mm. Tier 4 was defined as 5-10 adenomas, adenoma size > 10 mm, the presence of villous or tubulovillous features, or the presence of high-grade dysplasia. Tier 5 was defined as > 10 adenomas.
