Measure Description |
Time Frame |
---|---|---|
Eradication rate at different time intervals
Time Frame: immediately after the procedure
|
Both intention to treat (ITT) and per-protocol (PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infections in two groups.
The ITT analysis includes all randomly assigned patients who take at least one dose of the study medications.
The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.
