Figure 1 Pre‐ and post‐bronchodilator responses in all groups measured by resistance (Rrs) and reactance (Xrs) at 6, 8 and 10 Hz. Open circles and squares indicate outliers and extreme values, respectively. Post‐bronchodilator responses (shaded boxplots) were significantly different from pre‐bronchodilator responses (clear boxplots) for all parameters in all groups (p<0.05, Wilcoxon signed rank test). CF, cystic fibrosis; nCLD, neonatal chronic lung disease.
