Trends in Helicobacter pylori eradication rates by first-line triple therapy and related factors in eradication therapy.

Background/aims: Trends in successful eradication of Helicobacter pylori using first-line triple therapy, consisting of a proton pump inhibitor, amoxicillin, and clarithromycin, have been understudied. We evaluated H. pylori eradication rates at a single center over the last 10 years and identified risk factors related to eradication failure.
