Fig. 1 Study design: a 2-phase, randomized, placebo-controlled, crossover study. In the first phase a concentration-response study was performed either with methacholine or NKA in the absence of any drug treatment. During the second phase, each subject recruited went through all possible combinations of drug administration and challenge procedures. R, Random; Meth, methacholine; M, montelukast; P, placebo.
