Title: Development of the residential case-specular epidemiologic investigation method. Final report

Abstract

The residential case-specular method is an innovative approach to epidemiologic studies of the association between wire codes and childhood cancer. This project was designed to further the development of the residential case-specular method, which seeks to help resolve the ``wire code paradox``. For years, wire codes have been used as surrogate measures of past electric and magnetic field (EMF) exposure. There is a magnetic field hypothesis that suggests childhood cancer is associated with exposure to magnetic fields, with wire codes as a proxy for these fields. The neighborhood hypothesis suggests that childhood cancer is associated with neighborhood characteristics and exposures other than magnetic fields, with wire codes as a proxy for these characteristics and exposures. The residential case-specular method was designed to discriminate between the magnetic field and the neighborhood hypothesis. Two methods were developed for determining the specular of a residence. These methods were tested with 400 randomly selected residences. The main advantage of the residential case-specular method is that it may efficiently confirm or eliminate the suspicion that control selection bias or confounding by neighborhood factors affected the results of case-control studies of childhood cancer and magnetic fields. The method may be applicable to both past and ongoingmore » studies. The main disadvantage is that the method is untried. Consequently, further work is required to verify its validity and to ensure that sufficient statistical power can be obtained in a cost-effective manner.« less
