Figure 6 Subgroup analyses of adjusted polyp detection rate across withdrawal times. A: Adjusted polyp detection rate (PDR) plotted against effective withdrawal time stratified by bowel preparation quality; B: Adjusted PDR plotted against standard withdrawal time stratified by bowel preparation quality; C: Adjusted PDR plotted against effective withdrawal time stratified by physician seniority; D: Adjusted PDR plotted against standard withdrawal time stratified by physician seniority. PDR was adjusted for age, sex, Boston Bowel Preparation Scale, and endoscopist experience. PDR: Polyp detection rate; BBPS: Boston Bowel Preparation Scale.
