Removal from exposure, reduction in exposure (median: 56 months) |
36 of 44 eligible subjects (Participation rate: 82%) |
For subjects who avoided exposure (n=16), asthma severity decreased (p=0.001) and PC20 increased (p=0.002). For subjects who reduced their exposure (n=20), asthma severity decreased (p<0.001), and PC20 increased (p<0.001). But socioeconomic consequences (work disability, income loss) were more frequently associated with cessation than reduction of exposure (p<0.05). |
