Design outcomes

Primary

MeasureTime frameDescription
Helicobacter pylori Eradication RateSix to eight weeks after completion of the medicationHelicobacter pylori Eradication will be determined by ¹³C-urea breath test six to eight weeks after completion of the medication. The eradication rates will be evaluated by intention-to-treat (ITT) and per-protocol (PP) analysis.

Secondary

MeasureTime frameDescription
Rate of Adverse Drug Reaction(ADR)Within 7 days after completion of therapyAdverse drug reactions are classified into six types (with mnemonics): dose-related (Augmented), non-dose-related (Bizarre), dose-related and time-related (Chronic), time-related (Delayed), withdrawal (End of use), and failure of therapy (Failure).
Compliance RateWithin 7 days after completion of therapyCompliance was defined as poor when they had taken less than 80% of the total medication.
