Characteristics of patients: lung function

Patient number	FVC(% predicted)	FEV₁(% predicted)	FEV₁/FVC(%)	FEF_50%(% predicted)	Tlco(% predicted)	Tlco/Va(% predicted)
FVC, forced vital capacity; FEV₁, forced expiratory volume in 1 s; FEV_50%, forced expiratory flow at 50% of expired volume; Tlco, carbon monoxide transfer factor adjusted for haemoglobin; Tlco/Va, specific carbon monoxide transfer factor adjusted for haemoglobin.
