  2. aNot all subjects were prescribed aerosolized medications or airway clearance therapy during study. Correlations are based on individuals prescribed both aerosolized medication and airway clearance. The correlations involving two continuous variables are reported as Pearson’s r, while those involving a categorical variable are expressed as polychoric correlation coefficients. bRepresents number of unique children with CF to account for instances in which both parents participated in the study
