Hence, the use of an adenoma\u2010to\u2010polyp detection rate quotient and polyp detection rate (PDR) has been proposed to predict ADR. This study aimed to examine the usefulness of estimated ADR across different colonic segments in two age groups for Shenzhen people in China.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively analyzed 7329 colonoscopy procedures performed by 12 endoscopists between January 2012 and February 2014. The PDR, actual ADR, and estimated ADR of the entire, proximal, and distal colon, and within each colonic segment, in two patient age groups: &lt;50 and \u226550\u2009years, were calculated for each endoscopist.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The overall polyp and adenoma prevalence rates were 19.1 and 9.3%, respectively. The average age of adenoma\u2010positive patients was significantly higher than that of adenoma\u2010negative patients (54\u2009\u00b1\u200912.6\u2009years <jats:italic>vs<\/jats:italic> 42.9\u2009\u00b1\u200913.2\u2009years, respectively). A total of 1739 polyps were removed, among which 826 were adenomas. More adenomatous polyps were found in the proximal colon (60.4%, 341\/565) than in the distal colon (40.9%, 472\/1154). Overall, both actual and estimated ADR correlated strongly at the entire colon level and within most colonic segments, except for the cecum and rectum. In both age groups, these parameters correlated strongly within the traverse colon and descending colon.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Caution should be
