      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients will be assigned into two groups by simple randomization method. Allocation of patients to the study groups will be done by random-numbers table and using computer, and on this basis patients will be included in one of the two treatment groups. The implementation of the random allocation sequence occurs without knowledge of which patient will receive which treatment, Blinding description: Intervention (receiving dual therapy regimen or clarithromycin-based quadruple regimen) and patient evaluation will be carried out by a physician who is blinded to placement in treatment groups. Also patients and statistical analyzer will not know about patient grouping.</study_design>
