Model		Life time occupations were assessed in case-control studies during 1997-2003 and 2007-2009 using an ELF-EMF Job-Exposure Matrix for associating occupations with ELF exposure (¼T).
Details		AUTHORS' ABSTRACT: Carlberg, Hardell et al. 2017 (IEEE #6752): BACKGROUND: Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO. METHODS: Life time occupations were assessed in case-control studies during 1997-2003 and 2007-2009. An ELF-EMF Job-Exposure Matrix was used for associating occupations with ELF exposure (¼T). Cumulative exposure (¼T-years), average exposure (¼T), and maximum exposed job (¼T) were calculated. RESULTS: Cumulative exposure gave for astrocytoma grade IV (glioblastoma multiforme) in the time window 1-14 years odds ratio (OR) = 1.9, 95% confidence interval (CI) = 1.4-2.6, p linear trend <0.001, and in the time window 15+ years OR = 0.9, 95%CI = 0.6-1.3, p linear trend = 0.44 in the highest exposure categories 2.75+ and 6.59+ ¼T years, respectively.
