2	1.34	0.95–1.89
1	1.16	0.95–1.42
Never	1

All models are stratified on centre and age at baseline.

^*The model includes each occupational exposure separately and smoking status (never smoker (reference category), current smoker, former smoker), age at starting (continuous, for ever smoker), duration of smoking (continuous, for ever smoker), current quantity (continuous, among current smokers), a quadratic term for current quantity, two interaction terms (quantity*duration and age at starting*duration), a dummy variable for missing variables for current quantity, fruits and vegetables consumption (continuous variable, per 100g) and an interaction term between smoking status and fruits and vegetables consumption, and education.
