The Interphone study on use of mobile phones and brain tumour risk included 13 countries during the study period 2000 – 2004. The major results were published after a delay of 6 years in 2010. In the last decile of cumulative exposure > 1,640 h a statistically significant increased risk for glioma was found, OR = 1.40, 95 % CI =1.03-1.89. In the other categories of cumulative use a decreased risk was found. Bias and confounding were discussed as potential reasons for that. Analysing only subjects with regular use of a mobile phone yielded OR = 1.82, 95 % CI = 1.15-2.89 in the group with highest cumulative use.

There was an age difference between cases and controls in the Interphone study and furthermore cases and the matched controls were interviewed at different time periods, controls usually later than cases. This is problematic for mobile phone use with rapid…
