The study was managed by tertiary referral centers that had two research nurses who attended surveillance endoscopies to ensure that guidelines were followed. Additionally, all endoscopies were performed by a dedicated endoscopist. As part of the endoscopy visit, patients filled out questionnaires containing demographic and clinical data. Researchers also retrospectively collected any prior surveillance data for patients who had previously been under histologic and endoscopic surveillance.
Ms. Klaver and her colleagues had no financial conflicts of interest to report.
