Concentration-dependent induction of coughs to reach either C2 or C5. AITC cough challenge (Panels a and b), capsaicin cough challenge (Panels c and d). C2: the lowest concentrations of AITC or capsaicin which evoked two to four coughs; C5: the lowest concentrations of AITC or capsaicin which evoked five coughs or more. The solid lines with dots represent patients with chronic refractory cough (CRC) and the dashed lines with triangles represent healthy subjects
