Dependent variables	Entered variable(s)	Beta	value
ΔFEV1 (% of predicted)	Weight		0.000
	Height		0.010
	TCC		0.014
ΔFEV1/FVC	Baseline FEV1/FVC (%)		0.000
	TCC		0.001
	Asthma		0.013
ΔPEF	TCC		0.000
	Asthma		0.049
ΔFeNO	Baseline FeNO		0.000
	TCC		0.001

All the Δ values were the difference after 3 months. Variables of age, gender, asthma, TCC, body height, body weight, baseline levels of lung function parameters, or FeNO were included in the multiple linear regression analysis.
