Complementary roles of capsaicin cough sensitivity test and induced sputum test to methacholine bronchial provocation test in predicting response to inhaled corticosteroids in patients with chronic nonproductive cough

In the present study, we demonstrate that CCST and IST play complementary roles to MBPT. By combining the results of these tests, we are able to identify more patients with chronic nonproductive cough and treat patients more successfully with ICSs by improving the response rate to ICS treatment.
