Background : Helicobacter pylori infection, particularly with cagA -positive strains, is strongly associated with severe gastrointestinal outcomes such as peptic ulcer and gastric cancer, though the strength of this association varies across populations. This study investigates the link between cagA positivity and clinical diagnoses in Iranian patients to evaluate its potential as a predictor of disease severity in a high-prevalence region.
