Figure 1

Plot of forced expiratory volume in 1 second (FEV 1 ) as a function of airway size. The figure shows the plot of forced expiratory volume in 1 second (FEV1) to wall volume (left-hand side column) and airway lumen volume (right-hand side column) in never-smoker subjects. Panels A-D and panels E-H show the plots between FEV1 and extra-parenchymal airways and FEV1 and segmental (intra-parenchymal) airways, respectively. P < 0.0001 for the correlation coefficient (r) depicted in each panel.
