Figure 1. Individual data for bronchial hyperresponsiveness (BHR) to mannitol (provoking dose of mannitol to cause a 15% fall in forced expiratory volume in 1 s (FEV1), PD15), lung function (FEV1 % predicted), Asthma Quality of Life Questionnaire (AQLQ) overall score and Asthma Control Questionnaire (ACQ) score. The baseline negative BHR group (no BHR, n=9) had an inhaled corticosteroid (ICS) dose reduction over 12 weeks. The baseline positive BHR group (BHR, n=5) had an ICS dose increase over 12 weeks. Grey circles represent no BHR. *p<0.05.
