Associations between indices of asthma and risk factors among woodworkers; OR (95% CI) in logistic regression analyses, stratified by atopy
| Stratification by atopy | Asthma symptoms (n = 247)* | Work related asthma symptoms (n = 136)* | Asthma symptoms + BHR (n = 118)* | Clinical asthma (n = 181)* |
