4 Fig 3 The relationship between the maximal decrease in FEV1 from baseline during the EAR (left) and the LAR (right) after 2 consecutive allergen challenges performed in the same subjects (n = 28).

5 Fig 4 A, Relationship between the AUC during the LAR after 2 subsequent allergen challenges performed in the same subjects at least 3 weeks apart (n = 17, left) and power curves allowing estimation of sample size for expected attenuation of the LAR AUC (in a crossover study, right). Reproduced with permission from Gauvreau et al.49 B, Relationship between the percentage of sputum eosinophils at 7 hours (solid circles) and 24 hours (open circles) after 2 consecutive allergen challenges performed in the same subjects at least 3 weeks apart (n = 17, left) and derived power curves allowing estimation of sample size for expected attenuation of the allergen-induced percentage sputum eosinophils (crossover study, right).
