    Snippet: The sample size calculation was based on the primary study endpoint of incidence of all-cause AECOPD. Assuming that, on average, each subject is observed for a period So a sample size of 120 subjects should ensure sufficient precision in the estimation of the incidence rate of all-cause AECOPDs......
