Figure 2

A. Individual isolated exhaled breath condensate pH values immediately after coughing episodes in patients grouped by the response of their cough to a subsequent 1 month trial of proton pump inhibition. There are multiple samples collected from each subject. EBC acidification is significantly more common during cough in patients who subsequently respond to proton pump inhibition. B. Individual EBC pH data points plotted from 22 control subjects, for comparison.
