A meta-analysis was performed to evalutate the risk for intracranial tumors in relation to mobile phone use. Following twelve studies were included: Hardell et al. (Sweden, 1999), Muscat et al. (USA, 2000), Inskip et al. (USA, 2001), Johansen et al. (Denmark, 2001), Auvinen et al. (Finland, 2002), Hardell et al. (Sweden, 2002), Muscat et al. (USA, 2002), Lönn et al. (Sweden, 2005), Christensen et al. (Denmark, 2005), Schoemaker et al. (Nordic countries, 2005), Hardell et al. (Sweden, 2005), and Hardell et al. (Sweden, 2005).
|Reference group 1||unexposed|
|Group 2||mobile phone use: ever|
|Group 3||mobile phone use: at least 2 - 5 years|
748 cases used mobile phones for at least 2 - 5 years.
No increased pooled risk for all intracranial tumors related to mobile phone use was found. The results of this meta-analysis indicate that the use of mobile phones for up to 5 years does not increase the risk for intracranial tumors.
