^*See Methods section for formulas for calculating the following polyp burden measures: equally spaced weighted counts (ES), mid-range weighted counts (MR), and bottom-range weighted counts (BR). TC = sum of polyp counts in all size categories; TC2 = sum of polyp counts in the 2–4 mm and >4 mm categories.
