- Adjusted lung cancer rate ratios for several scenarios about the RR for ever smokers vs.
- no-smokers, assuming RRobs
a = 1.40 (95% C.I.: 1.30 - 1.51) for DEb exposure and smoking prevalence equal to 47.1% and 40.9% in the occupational cohort and the general population respectively.
-
a RRobs: observed risk ratio
-
b DE: diesel exhaust
-
c RRsmoking: risk ratio of smokers vs. non-smokers
-
d Inonexp: lung cancer mortality rate of non-DE exposed workers due to smoking
-
e Iexp: lung cancer mortality rate of DE exposed workers due to smoking
-
f bias factor = Iexp/Inonexp
-
g RRadj: adjusted risk ratio
-
h I0: lung cancer mortality rate of non-smokers
