Childhood cancer in relation to indicators of magnetic fields from ground current sources.

abstract：:We developed a new computer wire coding method and then applied it to investigate the suggestion that control selection bias might explain the observed association between wire codes and childhood cancer made in the study conducted by Savitz et al. in the Denver area. The computer wire coding method used a geographic ...
