Model		Mobile phone exposure and correlations with brain tumors - META analysis of prior studies
Details		The authors performed a meta-analysis of nine prominent studies looking at correlations between mobile phone use and brian tumor incidence. The studies included Auvinen (2002), Christensen (2005), Hepworth (2006), Inskip (2001), Lonn (2004, 2005), Muscat (2000), Shuz (2006), and Shoemaker (2005). The meta analysis did not include studies by Hardell because "there was insufficient data to calculate crude OR". A total of 5259 brain tumors (glioma, meningioma, acoustic neuroma). The authors report no overall effect on all brain tumors or their subtypes, although they do report a statistically significant effect for 10+ years of mobile phone use for all brain tumors as follows: OR = 0.86; 95% CI 0.7-1.05  high grade glioma, OR = 1.14; 95% CI 0.91-1.43  low grade glioma, OR = 0.64; 95% CI 0.56-0.74  meningioma, OR = 0.96; 95% CI 0.83-1.10  acoustic neuroma, OR = 0.90; 95% CI 0.81-0.99  pooled all brain tumors, OR = 1.25; 95% CI 1.01-1.54  10+ yr all brain tumors, OR = 1.22; 95% CI 1.06-1.41  analog vs digital, all brain tumors. Early users of mobile phones were also much more likely to use analog as opposed to digital technologies.
