1Data were log transformed before comparison.
2Data presented as percentage, value for Chi-square analysis.
3Data presented as mean ± standard deviation, values for Student -test.
FEV1: forced expired volume in 1 second; FVC: forced vital capacity; FEF25–75: forced expiratory flow 25%–75%; TLC: total lung capacity; FeNO: fractional expiratory nitric oxide.
