Association (coefficients (95% CIs)) between current or cumulative exposure to dust and asthma or rhinitis according to Poisson regression analysis
|
Asthma Estimate (95% CI) |
Rhinitis Estimate (95% CI) | |
| Model 1: | ||
| Current exposure | 0.34 (0.13 to 0.55) | 0.13 (0.05 to 0.21) |
| Sex | −0.20 (−1.0 to 0.63) | −0.08 (−0.35 to 0.19) |
| Model 2: | ||
| Cumulative exposure | 0.02 (−0.02 to 0.06) | 0.01 (−0.02 to 0.003) |
| Sex | −0.23 (−1.1 to 0.61) | 0.03 (−0.25 to 0.30) |
The fit (scaled deviance) of model 1 was 3.1 (3 df) and of model 2 was 2.7 (3 df) for asthma and 3.6 and 4.0 for rhinitis, respectively.
The two models are log (incidence)=K11+K12×current exposure+K13×sex (0=women, 1=men) and log (incidence)=K21+K22×cumulative exposure+K23×sex, K11 to K23 are constants.
