a
Models adjusted for smoking pack-years.
b
Models adjusted for age and smoking pack-years.
c
Model with different comparison group from above.
d
Comparison group are those not spending work time in both grinding/packaging and flavoring areas; this includes workers spending work time in one or the other of these areas.
e
Comparison group are those not spending work time in either grinding/packaging or flavoring areas.
