Lung function and secondhand smoke exposure among children with cystic fibrosis: A Bayesian meta-analysis.

Background: Secondhand smoke exposure, an important environmental health factor in cystic fibrosis (CF), remains uniquely challenging to children with CF as they strive to maintain pulmonary function during early stages of growth and throughout adolescence. Despite various epidemiologic studies among CF populations, little has been done to coalesce estimates of the association between secondhand smoke exposure and lung function decline.

Methods: A systematic review was performed using PRISMA guidelines.
