a FEV1%: The percent of forced expiratory volume in 1 second in prediction; FEV1/FVC: forced expiratory volume in 1 second / forced vital capacity; FVC%: the percent of forced vital capacity in prediction; MEF25% FVC, MEF50% FVC, MEF75% FVC: midexpiratory flow; MMEF: maximal midexpiratory flow; PEF: peak expiratory flow.
