Figure 4

Relationship between generation and airway narrowing to carbachol administered to the adventitial airway surface. Plots are from four different airway preparations. Airway narrowing was quantified by the percentage decrease in luminal cross sectional area (% CSA). Airway narrowing was increased at more distal locations indicated by positive correlations between narrowing and airway generation in each preparation. Linear equations of best fit are indicated for each airway. (Pearson's correlation analysis)
