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.
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.

| Setup | test person's head exposed |
| Sham exposure | A sham exposure was conducted. |
No parameters are specified for this exposure.
The results of the meta-analysis suggest that a substantial short-term impact of radiofrequency electromagnetic fields emitted by mobile phones on cognitive performance can be ruled out.
