Participation Rate67.5% (81 of 120) of farmers with occupational asthma who were invited to take part in educational intervention.
Intervention EffectivenessIn the educational intervention group: 1. The proportion of subjects reporting at least one current respiratory symptom at work was significantly reduced (p=0.012). 2. The geometric mean of exhaled nitric oxide fraction (FeNO) significantly decreased from 28.2 to 25.7 ppb (p=0.042). 3. In 32 subjects with an elevated baseline FeNO (>35 ppb), FeNO significantly decreased from 59.7 to 49.2 ppb (p=0.003).
