Histograms of endoscopist-specific polypectomy rates estimated from hierarchical logistic regression models among A) gastroenterologists and B) surgeons. Models were adjusted for patient age (50-54/55-59/60-64/65-70/70-75), sex, family history of colorectal cancer, colonoscopy in the past 10 years, and colonoscopy indication (screening was defined as no history of gastrointestinal conditions and no lower abdominal symptoms in the past 6 months.). Covariates were centered such that the rates are interpretable as endoscopist-specific rates for typical patients.
