| Wood dust* | 1.27 (0.92 to 1.76) | 1.18 (0.45 to 3.06) | 1.25 (0.88 to 1.77) |
| n=51 | n=5 | n=46 | |
The risks are shown among groups with non-overlapping exposures to inorganic dust, chemicals, and wood dust, adjusted for age and smoking based on Poisson regression models. There were no cases among the metal-fume-exposed workers.
