Comparison Study of Airway Reactivity Outcomes due to a Pharmacologic Challenge Test: Impulse Oscillometry versus Least Mean Squared Analysis Techniques
Figure 4
Plots of mean (±SEM) values for respiratory resistance , as a function of oscillatory frequency, before (pre) and after (post) bethanechol . As shown, significant differences in the middle oscillatory frequencies range are displayed ; paired -test one tailed at each frequency and overall .
