Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Helicobacter pylori eradication rate	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	Rate of adverse effects	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
Secondary	Compliance rate	Compliance was defined as poor when they had taken less than 80% of the total medication	Within 7 days after completion of therapy
