Comparison of polyp location, size, and tumor burden in Apc^Min/+ and Apc^Δ242/+ mice at 120 days of age. a Average polyp numbers detected in the proximal, middle, and distal portions of the small intestine and colon. b Average polyp sizes detected in the proximal, middle, and distal portions of the small intestine and colon. Diameters of polyps were measured and reported in mm. c Tumor burden in the proximal, middle, and distal portions of the small intestine and colon. Tumor burden was calculated using the formula (4/3)πr³. *P < 0.05; **P < 0.005; ***P < 0.001. n = 15 for Apc^Min/+ mice and n = 18 for Apc^Δ242/+ mice. Error bars represent standard deviation
