Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Eradication rate of Helicobacter pylori | At least 4 weeks after completion of therapy | Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Eradication rate of Helicobacter pylori susceptible strains | At least 4 weeks after completion of therapy | Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value). The antibiotic susceptible strains were assessed using the E test method. |
| Eradication rate of Helicobacter pylori resistant strains | At least 4 weeks after completion of therapy | Eradication of Helicobacter pylori was defined as negative result of urea breath test (\<4‰ cut-off value). The antibiotic resistant strains were assessed using the E test method. |
