Table 1 Predicted prevalence of severe and moderately severe BHR with changes in population BHR [Based on data from reference [14]]

From: A half doubling dose change in bronchial hyperresponsiveness in a population represents an important difference

Doubling dose worsening in population BHR Change in Prevalence Rate ratio (95% CI) Prevalence of moderately severe BHR, % (95% CI) Prevalence of severe BHR, % (95% CI)
Baseline - 41.2 6.6
0.25 1.15 (1.12-1.17) 47.3 (46.3-48.1) 7.6 (7.4-7.7)
0.5 1.31 (1.26-1.36) 54.2 (52.1-56.2) 8.7 (8.3-9.0)
0.75 1.51 (1.42-1.59) 62.2 (58.6-65.6) 10.0 (9.4-10.5)
1.0 1.73 (1.60-1.86) 71.4 (65.9-76.6) 11.4 (10.6-12.3)
