Where possible, we defined BE cases according to long- (≥3 cm) (n = 118) vs. short-segment (<3 cm) BE (n = 200), and newly diagnosed BE (first evidence of BE on study EGD) (n = 208) vs. prevalent BE (self-reported diagnosis of BE or history of BE diagnosis on review of the electronic medical record before the study EGD) (n = 109).
