  • Data are presented as mean±sd, with the exception of predicted residual volume (RV) levels, which were positively skewed and are stated as median values with ranges. FEV1: forced expiratory volume in one second; FVC: forced vital capacity; DL,CO: diffusing capacity of the lung for carbon monoxide; ns: nonsignificant.
