Adjusted rate ratios for several scenarios about the smoking prevalence in the general population (Pr(r)) and assuming a lung cancer RR for ever smokers vs. non-smokers equal to 10.7 or equal to 12 (SMRobsa = 2.18 (95% C.I.: 1.61 - 2.87), smoking prevalence in the occupational cohort 84%).
a SMR: standardized lung cancer mortality rate comparing (diesel exposed) workers versus the general population (see table 3 for further definitions).
