Mobile phone and cordless phone use and the risk for glioma - Analysis of pooled case-control studies in Sweden, 1997–2003 and 2007–2009
Abstract
We made a pooled analysis of two case-control studies on malignant brain tumours with patients diagnosed during 1997-2003 and 2007-2009. They were aged 20-80 years and 18-75 years, respectively, at the time of diagnosis. Only cases with histopathological verification of the tumour were included. Population-based controls, matched on age and gender, were used. Exposures were assessed by questionnaire. The whole reference group was used in the unconditional regression analysis adjusted for gender, age, year of diagnosis, and socio-economic index. In total, 1498 (89%) cases and 3530 (87%) controls participated. Mobile phone use increased the risk of glioma, OR=1.3, 95% CI=1.1-1.6 overall, increasing to OR=3.0, 95% CI=1.7-5.2 in the >25 year latency group. Use of cordless phones increased the risk to OR=1.4, 95% CI=1.1-1.7, with highest risk in the >15-20 years latency group yielding OR=1.7, 95% CI=1.1-2.5. The OR increased statistically significant both per 100h of cumulative use, and per year of latency for mobile and cordless phone use. Highest ORs overall were found for ipsilateral mobile or cordless phone use, OR=1.8, 95% CI=1.4-2.2 and OR=1.7, 95% CI=1.3-2.1, respectively. The highest risk was found for glioma in the temporal lobe. First use of mobile or cordless phone before the age of 20 gave higher OR for glioma than in later age groups.

“In the leave-one-out meta-analysis of glioma risk among long-term (10+ years) mobile phone users, performed on the MA5 dataset using the random effects models − REML method, we identified one influential study (Hardell and Carlberg, 2015), whereby the 95 % confidence interval of the mRR obtained excluding it (0.87–1.08) does not include the point estimate of the overall mRR (1.13) (Table 9).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
