Correlations between FeNO and IOS parameters in patients with asthma

Groups	Parameters		lnZrs	lnFres	lnR5	lnR20	lnR5-R20	X5
*P<0.05; ln: Data were converted by natural logarithmic transformation. CVA: Cough variant asthma. TA BPT(+): Typical asthma with positive bronchial provocation test. TA BDT(+ ): Typical asthma with positive bronchial dilation test. Fres: Resonant frequency; Zrs: Respiratory Impedance, R5: Resistance at 5 Hz; R20: Resistance at 20 Hz; X5: Reactance at 5 Hz
