Synoptic Analysis of Epidemiologic Evidence of Brain Cancer Risks from Mobile Communication. epidem.

Published in: J Electromagn Anal 2014; 6 (14): 413-424

Aim of study (acc. to author)

A synoptic analysis was conducted on all data from case-control studies on the association between mobile phone use and brain tumors published between 2001 and 2014. In this new synoptic approach, all available risk estimates (odds ratios) of the identified studies were presented and analyzed without further selection criteria such as the size of the study or exposure metric.

Endpoint/type of risk estimation

Type of risk estimation:

Exposure

Population

Conclusion (acc. to author)

The relation between odds ratios reported in the publications and 1) number of exposed cases, 2) ratio of the number of controls and the number of cases, 3) year of publication, 4) the cumulated years of use, 5) cumulated call time and 6) cumulated number of calls were presented in figures.
Two quite different data pools could be identified with numerous studies from one single research group (Swedish Hardell group) opposing all other national and international studies.
It could be shown that with the increasing number of exposed cases both data pools exhibit a clear trend of risk estimates (odds ratios) towards a reduced cancer risk (OR 0.8).
Overall, the synoptic analysis supports reassuring rather than alarming conclusions on health risks from mobile telecommunication.
