Figure 7: Evolution of (a), (b), (c), and (d) descriptors at different times after elastase instillation. is the mean equivalent diameter, and are weighted indexes of airspace size distribution, and is the mean linear intercept. Statistically significant differences between the control ( ) and the elastase-treated ( ) groups are indicated as well as differences between successive time points in the elastase group ( ,*).
