Title A philosophy for dealing with hypothesized uncontrolled confounding in epidemiological investigations
Bibliographic information Mar.-Apr. 1995, Vol.86, No.2, p.106-110. 11 ref.
Abstract Paper presented at the 10th International Symposium on Epidemiology in Occupational Health (Como, Italy, 20-24 Sep. 1994). It argues that the issue of uncontrolled (i.e whose effects have not been taken into consideration by the study) confounding should only be raised during the discussion of the results of an epidemiological investigation if certain conditions are satisfied. These conditions are: the putative confounder has been identified and has been shown to be associated with both the exposure and disease under investigation; the association between the proposed confounder and the exposure and disease of interest has been quantified; the likely effect of the proposed confounding on the results of the investigation can be calculated. The example of studies of the relationship between occupational exposure and lung cancer, with tobacco smoking as the confounding factor, is discussed in detail.
