Figure 28Mean difference in the maximum percent decrease in FEV1 following ECT with prophylactic therapy relative to placebo

NOTE: The reduction in FEV1 post-exercise challenge with prophylactic therapy was compared with FEV1 post-exercise challenge with placebo (i.e. placebo response - prophylactic response), and therefore negative values favor the prophylactic pre-treatment.
