Figure 4

Correlation of number of methacholine-induced cough with deep inspiration (DI) effect on methacholine-induced bronchoconstriction (a), concentration of inhaled methacholine (b), intensity of methacholine-induced bronchoconstriction assessed by FEV1 (c) and intensity of methacholine-induced bronchoconstriction assessed by PEF40 (d). Concentration of methacholine in this case means the concentration causing 20% or more fall in FEV1 in individual subjects.
