Subject flow diagram. This diagram summarizes the flow of study subjects from screening for eligibility through 6 months post-initial treatment. Eighty subjects were initially enrolled at baseline, 65 completed the 3-month follow-up, and 60 completed the 6-month follow-up.

5. Figure 4
Significant relationships at baseline with cough severity. Using multivariate analysis of covariance, statistically significant associations that persisted after adjustment were education, ability to speak bothered by cough, and urge to cough. Worse cough severity at baseline (mean ± SE) was associated with less than a college education, worse ability to speak, and worse urge to cough.

6. Figure 5
Significant relationships at baseline with cough-related quality of life (CQOL). Using multivariate analysis of covariance, statistically significant associations that persisted after adjustment were age, UI, ability to speak bothered by cough, use of self-prescribed remedies, and depression symptoms. Worse CQOL at baseline (mean ± SE) was associated with younger age, worse UI, worse ability to speak bothered by cough, use of self-prescribed remedies, and worse depression symptoms. QOL = quality of life; RX = self-prescribed remedies; UI = urinary incontinence.

7. Figure 6
Significant relationships since baseline in cough severity. Using multivariate analysis of covariance, significant associations that persisted after adjustment were education, sex, ability to speak bothered by cough, and urge to cough. Greater improvement in cough severity since baseline (mean ± SE) was associated with less than a college education, male sex, greater improvement in ability to speak, and greater improvement in urge to cough. Negative scores reflect improvement.

8. Figure 7
Significant relationships since baseline in cough quality of life (CQOL). Using linear mixed models, significant associations that persisted after adjustment were use of self-prescribed remedies, UI, urge to cough, and anxiety symptoms. Greater improvement in CQOL since baseline (mean ± SE) was associated with the use of self-prescribed remedies, greater improvement in UI (most improvement = better), greater improvement in urge to cough, and greater improvement in anxiety symptoms. Negative scores reflect improvement. See Figure 5 legend for expansion of abbreviations.
