Low-grade dysplasia diagnosis ratio and progression metrics identify variable Barrett’s esophagus risk stratification proficiency in independent pathology practices

The diagnosis of low-grade dysplasia (LGD) in Barrett's esophagus (BE) is subject to substantial interobserver variation. Our central aim in this study is to compare independent pathology practices using objective measures of BE risk stratification proficiency, including frequency of diagnosis and rate of progression to high-grade dysplasia (HGD) or adenocarcinoma (EAC) after the first diagnosis of LGD.
