Figure 3

Menthol nasal challenges decreased cough sensitivity, what is demonstrated by the higher capsaicin concentrations for the cough threshold C2 (upper panel) compared to the data obtained after nasal vehicle and saline data (both isomers p<0.05 for C2). Cumulative cough counts and total cough response after nasal (+) and (−) menthol challenges decreased significantly compared to the saline and vehicle values p< 0.01. Regression analysis showed similar differences *p<0.05, **p<0.01.
