cqvip:Background. This study was conducted to investigate the strength of agreement between the endoscopic atrophic border(EAB) and the histological score for atrop hy. Methods.A series of 298 dyspeptic Japanese patients underwent upper endoscop y. The grade of gastric atrophy was estimated according to the EAB. Antral and c orpus biopsy specimens were taken and were evaluated semiquantitatively accordin g to the updated Sydney classification system, including the score for atrophy. The StatExact software package was used to calculate the weighted kappa statisti cs. Results. The strength of agreement between the endoscopic atrophy score (EAB ) and the histological atrophy score was good, with a weighted kappa value of 0. 51 (95%confidence interval, 0.44-0.59). Conclusions.T- he strength of agreement between the end oscopic and histological atrophy scor es is not worse than the interobserver histological agreement between two pathol ogists. It is worthwhile to carry out further research on the use of the EAB to identify and score gastric atrophy.
