Risk of study outcomes in patients with prevalent chronic obstructive pulmonary disease. In population 1, the IRRs of moderate and severe exacerbation and pneumonia during the PPI treatment period were calculated, compared to that at the baseline. Population 2 comprised patients with an observation period of at least 90 days after PPI discontinuation, and the IRRs of moderate and severe exacerbation and pneumonia during the PPI treatment and post-treatment periods were calculated.
