AIM: This study used the OLGA system to characterize the histology pattern of @entity3621 in dyspeptic outpatients with a mean age of 45 years from regions with different @entity356 risks. BACKGROUND: Several classification systems have been purposed for understanding the status of the gastric mucosa. Currently, the Sydney system is the most widely employed. Nevertheless, the applicability of the Sydney system in therapeutic and prognostic areas is a matter of debate. Given this shortcoming an international group of gastroenterologists and pathologists developed a new system named Operative Link on Gastritis Assessment (OLGA). @entity1 AND METHODS: In this cross-sectional comparative study the OLGA system was used to characterize the histology pattern of @entity3621 in 685 dyspeptic @entity1 referring to the department of gastroenterology of a training hospital. RESULTS: No significant correlation was found between active inflammation and total OLGA score (P > 0.05). Also, no statistically significant correlation was found between activity and @entity1944 , @entity1141 , @entity194 , and @entity5 (P > 0.05). Even though, there is a positive correlation between mild @entity32 and total OLGA score, no correlation has been identified between chronicity and @entity1141 or @entity5 (P > 0.05). Nearly, In all cases with  no @entity1141 OLGA score  was  zero but all @entity1 with @entity356 OLGA score was more than two. CONCLUSION: Generally, the activity is not a useful factor in predicting prognosis and its loss of relation with total OLGA score does not make OLGA score any less predictable.
