Activity InterventionRemoval from exposure, transferal to low exposure area (mean: 14 months)
Participation RateLimitation: no report of participation rate
Intervention EffectivenessNine of 29 subjects were asymptomatic at follow-up, all of whom ceased exposure. Subjects who continue with intermittent exposure (n=7) and daily exposure (n=4) were still symptomatic at follow-up and required pharmacological treatment. For subjects who ceased exposure (n=18), asymptomatic at follow-up was associated with shorter duration of symptoms before diagnosis, higher FEV1 and PD20 at presentation, higher FEV1 at follow-up (p<0.05), and lower bronchial reactivity at follow-up.
