Lung cancer risk in relation to cigarette consumption and years of work as baggers (subjects with known duration of work)

TermsORCIp value
Estimated using conditional logistic regression analysis for stratified data (strata: five year age): model terms (TERMS), odds ratio (OR), exact 95% confidence interval (CI), exact error probability (p) for two tailed test.
*OR = 1 among non-smokers.
†OR = 1 among subjects: never exposed to PVC dusts; exposed to PVC but not baggers; and baggers with unknown duration of work.
