PDR: polyp detection rate; ADR: adenoma detection rate; proximal PDR: detection rate of polyps proximal to the splenic flexure; distal PDR: detection rate of polyps distal to the splenic flexure; proximal ADR: detection rate of adenomas proximal to the splenic flexure; distal ADR: detection rate of adenomas distal to the splenic flexure.
