Abstract
Objectives: There is concern regarding the possible health effects of cellular phone
use. We examined whether the source of funding of studies of the effects of low-level
radiofrequency radiation is associated with the results of studies. We conducted a
systematic review of studies of controlled exposure to radiofrequency radiation with
health related outcomes (electroencephalogram, cognitive or cardiovascular function,
hormone levels, symptoms and subjective wellbeing).
Data sources: We searched Embase, Medline and a specialist database in February
2005 and scrutinised reference lists from relevant publications.
Data extraction: Data on the source of funding, study design, methodological quality
and other study characteristics were extracted. The primary outcome was the
reporting of at least one statistically significant association between the exposure and
a health related outcome. Data were analysed using logistic regression models.
Data synthesis: Of 59 studies, 12 (20%) were exclusively funded by the
telecommunications industry, 11 (19%) were funded by public agencies or charities,
14 (24%) had mixed funding (including industry) and in 22 (37%) the source of
funding was not reported. Studies exclusively funded by industry reported the largest
number of outcomes but were least likely to report a statistically significant result: the
odds ratio was 0.11 (95% confidence interval 0.02 to 0.78), compared to studies
funded by public agencies or charities. This finding was not materially altered in
analyses adjusted for the number of outcomes reported, study quality and other
factors.
Conclusions: The interpretation of results from studies of health effects of
radiofrequency radiation should take sponsorship into account.
