Hardell L, Mild KH, Carlberg M. (2003):

This paper is yet another analysis of the case-control study first reported in the European Journal of Cancer Prevention in 2002. Much of the methodology description is identical to that in the paper in International Journal of Radiation Biology (2002b) and several of the Tables use the same format. However, the matching is dropped and the analyses are performed using all the cases (1429) and controls (1470) who answered the questionnaire. In the discussion section of the paper one other difference from the first paper is mentioned. The unexposed group only contains those without any RF exposure, while in the earlier paper the unexposed group could contain subjects with exposure to other phone types. A total of 179 different statistical analyses are reported, which increases the likelihood of statistically significant results having been obtained by chance. Some of the statistically significant results are surprising - for instance the Odds Ratio for cordless phones for astrocytomas of 1.5 is unusual, given that cordless phones, which use extremely low power in Sweden, have never been implicated in brain tumours. Also, the Odds Ratio of 3.7 for contralateral use of an analogue phone for acoustic neuroma is difficult to explain.
