Objective evaluation of (a) quantitative improvement of the Total Nasal Inspiratory Airflow at population level and (b) quantitative improvement of the Maximal Midexpiratory Flow at population level. a Smoothed frequency distribution of V’na values (expressed as percentage (%) of the expected value) measured before (pre) and after (post) nebulization. b Smoothed frequency distribution of MMEF 25/75 values (considered as percentage (%) of the expected values) measured before (pre) and after (post) nebulization
