Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Helicobacter pylori eradication rate
Time Frame: four to six weeks after completion of the medication
Helicobacter pylori Eradication will be determined by ¹³C-urea breath test four to six weeks after completion of the medication. The eradication rates will be evaluated by intention-to-treat (ITT) and per-protocol (PP) analysis.
four to six weeks after completion of the medication

Secondary Outcome Measures

Outcome Measure
