Figure 4.

Bland-Altman plots. Individual differences in the degree of MCh-induced bronchoconstriction between invasively measured EF₅₀ and GL and between EF₅₀ and Cdyn, are plotted against the average corresponding values (expressed as PD50, μg MCh). The solid line represents the mean of the differences, the dashed lines show the upper and lower limits of agreement.
