In Reply: Dr Shah and colleagues note that representation of black patients in the Clinical Outcomes Research Initiative (CORI) endoscopic database (6.4%) is significantly lower than the prevalence of black persons in the US population (13.4%). In a separate analysis, we compared the demographics of individuals aged 65 years and older in our database with a Medicare data set and found the endoscopic database to be representative.1 Therefore, the CORI database does appear to reflect the population that receives endoscopic procedures.
