To be classified as triple treatment, one drug from either the proton pump inhibitor (PPI) or H2-receptor antagonist group combined with one macrolide and one other antibiotic. Both antibiotics had to be redeemed on the same date, whereas the PPI or H2-receptor antagonist could be redeemed within 60 days preceding antibiotics. Individuals redeeming prescriptions for PPIs or H2-receptor antagonists combined with either amoxicillin and metronidazole or tetracycline and metronidazole were also classified as triple treated
