Results of the logistic regression analysis for respiratory symptoms and diseases with relation to cumulative exposure in fibreyears, adjusted for factory, age, smoking habits, and gender

Cumulative exposure in fibreyears (f/m3 × years)
0≤3>3
Results expressed as OR (95% CI). Cumulative exposure of less than 3 fibreyears has been used as reference if there were no controls with symptoms or diseases.
