  • PC20 methacholine and AMP are expressed as means with 95% CI. All other parameters are expressed as medians with interquartile ranges.

  • DC = doubling concentrations; ECP = eosinophilic cationic protein.

  • p⩽0.05 (tested with ANOVA or Kruskal-Wallis).

  • 2-150 FP2000 versus prednisolone;

  • 2-160 FP2000 versus FP500;

  • 2-152 prednisolone versus FP500.

  • 2-165 p value in last column is for the difference between all three treatment groups by ANOVA or Kruskal-Wallis test.
