Zusammenfassung:We conducted a meta-analysis to acquire an understanding of the association between leukemia and occupational exposure to electric an magnetic fields. To explore sources of heterogeneity, study characteris were scored and examined using regression analysis. While most studie present a small elevation in risk, the apparent lack of a clear pattern of exposure to EMF and risk of leukemia substantially detracts from the hypothesis that measured magnetic fields in the work environment are responsible for the observed excess risk of leukemia. Findings were no sensitive to assumptions, influence of individual studies, weighting schemes, and modeling. Some evidence of publication bias is noted.
