Adenomas detected with standard forward-viewing colonoscopy Adenomas detected with full-spectrum colonoscopy Total number of adenomas identified Adenoma miss rate with standard forward-viewing colonoscopy* Adenoma miss rate with full-spectrum colonoscopy*
Standard forward-viewing colonoscopy first (n=88) 29 20 49 20/49 (41%);† 27·0–56·0 ..
Full-spectrum colonoscopy first (n=97) 5 62‡ 67 .. 5/67 (7%); 2·5–16·6

Data are n or n/N (%) with 95% CI.
