Description

Excerpt: Morgan et al. (1) concluded that cystic fibrosis (CF) in children and adolescents with a high baseline forced expiratory volume (FEV1) were less likely to have a therapeutic intervention or slower rate of FEV1 decline after a single acute decline in FEV1 of 10%. This conclusion is not well supported due to the arbitrary criteria used for defining a pulmonary exacerbation, as explained below.
