Activity Intervention Removal from exposure (>1 yr)
Participation Rate112 of 140 eligible subjects (Participation rate: 80%)
Intervention EffectivenessThose removed from exposure (n=78) were worse off financially, had fewer respiratory symptoms than the group who remained exposed (n=34), and their percent predicted FEV1 improved by 4-6%. Improvement in respiratory symptoms was associated with duration of symptoms before diagnosis (p=0.001), higher FEV1 at presentation (0.008), earlier development of symptoms after first exposure (p>0.05), and earlier removal from exposure (p>0.05).
