  1. *P < 0.05 was considered statistically significant
  2. Abbreviations: VCmax Maximum vital capacity, FVC Forced vital capacity, FEV1 Flow expiratory volume in 1 s, FEF25-75 Forced expiratory flow at 25% to 75% of the FVC, DLCO Lung diffusion for carbon monoxide, the values were adjusted for hemoglobin
  3. Note: All the tests are expressed as percentage of theoretical values for sex, age, and height. Continuous variables are presented as mean ± SD. Non-parametric variables were expressed as median and IQR
