  1. LC latent class, CI confidence interval, PI probability interval; Bayesian analog of the confidence interval. GL gastric lesion, GDL glandular lesion, SQL squamous lesion, CSL clinically significant lesion
  2. aCalculated relative to direct observation of lesions via endoscopy as the gold standard but adjusted for repeated measurements using mixed-effects logistic regression
  3. bBased on Bayesian latent class analysis with sucrose tests evaluated at the 24 µmol/L cut-off and endoscopy assumed to be an imperfect test
