Values are means (standard errors). P-values are from ANCOVA adjusted for body length at testing, gender, race, and GA at delivery. VA – alveolar volume; DL – lung diffusion; FVC – forced vital capacity; FEV0.5 – forced expired volume in 0.5 seconds; FEF75 – forced expiratory flow at 75% FVC; FEF50 – forced expired flow at 50% FVC; FEF25–75 – forced expiratory flow between 25% and 75% FVC.
