  1. Numbers or mean values and standard deviations (SD) are given
  2. VC  vital capacity determined in the single-breath manoeuvre within the assessment of diffusing capacity, FeNO  fractional concentration of exhaled nitric oxide. Predicted values were taken from those for forced vital capacity of the Global Lung Function Initiative (GLI). BMI  body mass index. *Geometric mean and standard deviation (in parentheses, to be interpreted as variability factor of the geometric mean)
