What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Helicobacter pylori eradication rate
Time Frame: Six weeks after completion of therapy
Six weeks after completion of therapy, H. pylori eradication was assessed by ¹³C-urea breath test. Eradication was defined as negative result from urea breath test (<4‰) (4‰ as the cutoff value).
Six weeks after completion of therapy

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of adverse effects
Time Frame: Within 7 days after completion of therapy
The subjects were asked to grade the severity of adverse events according to their influence on daily activities, experienced as "mild" (transient and well tolerated), "moderate" (causing discomfort and partially interfering with daily activities), or "severe" (causing considerable interference with daily activities)
Within 7 days after completion of therapy
Compliance rate
