Association between possible MFF and welding related respiratory symptom suggestive of welding related asthma and increase in bronchial responsiveness in multiple logistic regression analysis*
| At least one welding related respiratory symptoms (n = 32) | Persistent welding related respiratory symptoms (n = 19) | Increase in BR (n = 23) | |
|---|---|---|---|
| OR (95% CI) | OR (95% CI) | OR (95% CI) | |
| *The ORs for the model have been adjusted for age, smoking, atopy, physician diagnosed asthma, symptoms of non-welding related asthma, and immunological sensitisation to metals. | |||
| BR, bronchial responsiveness defined as a 3.2-fold decrease in PC20. | |||
| Possible MFF (n = 91) | 4.92 (2.10–11.52) | 13.72 (3.63–51.84) | 1.26 (0.49–3.24) |
