Characterising airway obstructive, dysanaptic and PRISm phenotypes of prematurity-associated lung disease

Abstract

Introduction Although obstructive airway disease has been shown to be associated with prematurity, other spirometry phenotypes are less well described. Objectives We characterised abnormal spirometry phenotypes in preterm-born children, including prematurity-associated obstructive lung disease (POLD, forced expiratory volume in 1 s (FEV 1)
