||Towards causal inference in occupational cancer epidemiology - II. Getting the count right
||Apr.1993, Vol.37, No.2, p.181-189. Illus. 13 ref.
||This paper assesses causal inference in occupational cancer epidemiology and highlights the importance of using the right data sources when examining the association between exposure and tumour incidence. At first the study was confined to a mortality analysis using death certificates but it became apparent that several cases had outlived the end-date of the study or had died of an unrelated cause not associated with tumours. The study was changed to include morbidity (incidence) data using cancer registration. Some guidelines, which derive from perusal of the five-year relative survival rates (RSR) and of the ratio of cancer registrations to deaths (R/D) are put forward to help researchers in deciding whether mortality or morbidity is the appropriate statistic for the analysis contemplated.
