  1. Data are presented as mean ± SD.
  2. Abbreviations: FVC: vital capacity; FEV1: forced expiratory volume in one second; FRC He: functional residual capacity by the helium technique; FRC Pl: functional residual capacity measured by plethysmography, SpO2: transcutaneous oxyhemoglobin saturation, Rsint: airway resistance by the interruption technique, % Pred: values are expressed as a percentage of predicted value. # height is expressed as the armspan in neuromuscular patients.
  3. The controls were compared to the pooled patients using the Student t test or Chi-squared test where appropriate. Comparison between the 3 groups of patients was performed with the Kruskal Wallis rank sum test. #Weight was significantly lower in the patients with cystic fibrosis compared to the other patients. §The asthmatic patients had a significantly better lung function than the two other groups, no significant differences were observed between patients with cystic fibrosis and those with neuromuscular disease. NP: not performed, NS: not significant.
