The distribution of nesfatin-1 was skewed while visfatin was normally distributed; therefore Spearman's rho and Pearson's r were used to analyze the correlations of NUCB2/nesfatin-1 and visfatin, respectively, to the other parameters presented.
FEV1: forced expiratory volume in 1 second; FENO0.05: fractional exhaled nitric oxide concentration at exhalation flow rate of 50 mL/s; Hb-D L,CO/V A: diffusing capacity for carbon monoxide per unit of alveolar volume standardized for haemoglobin; IL: interleukin; TNF: tumor necrosis factor.
