Abstract:
|
On the basis of longitudinal survey data from the Nurses' Health Study, we investigate women's lung cancer rates with respect to smoking exposure using threshold regression methodology. Smoking history, smoking status, and pack-years were used to measure smoking exposure. We calculate age and exposure-specific lung cancer rates and obtain hazard ratios for smokers and nonsmokers. We compare our results with those provided by a proportional hazards approach.
