Fig. 1From: Antibiotic duration and changes in FEV1 are not associated with time until next exacerbation in adult cystic fibrosis: a single center studyHypothetical Course of Cystic Fibrosis Pulmonary Exacerbations. This figure illustrates the hypothetical course of changes in lung function (defined as FEV1 in this study) over time. Our main outcome of interest was time until next exacerbation (TUNE). For each exacerbation, we examined the “drop” in FEV1 (change in FEV1 from baseline at onset of exacerbation), “recovery” of FEV1 (change in FEV1 over the course of treatment of exacerbation) and duration of intravenous (IV) antibiotics as covariatesBack to article page
