No effects of short-term exposure to mobile phone electromagnetic fields on human cognitive performance: A meta-analysis. med./bio.

Published in: Bioelectromagnetics 2012; 33 (2): 159-165

Aim of study (acc. to author)

To clarify whether there is an impact of mobile phones on human cognition by conducting a meta-analysis based on a large pool of studies.

Background/further details

The meta-analysis was carried out as a group comparison between exposed and non-exposed subjects. Altogether, the current analysis is based on 749 subjects.
The following 17 studies were included: Besset et al. 2005, Curcio et al. 2004, Curcio et al. 2008, Edelstyn et al. 2002, Haarala et al. 2003, Haarala et al. 2004, Haarala et al. 2007, Keetley et al. 2006, Koivisto et al. 2000a, Koivisto et al. 2000b, Lee et al. 2003, Luria et al. 2009, Regel et al. 2007, Russo et al. 2006, Sauter et al. 2011, Terao et al. 2006, Unterlechner et al. 2008.
