a years since first regular use (one call per week or more over a period of six months or longer) of ten years or more
b ipsilateral use: preferred side of the head during mobile phone use corresponds to the side of the head where the tumour is located; contralateral use: preferred side of the head during mobile phone use corresponds to the side of the head opposite to the tumour
c relative risk estimated by the odds ratio and 95% confidence interval
d ratio of the relative risk estimates for ipsilateral use by contralateral use
e defined as never being a regular user (never one call per week or more over a period of six months or longer) or becoming a regular user less than 1.5 years ago in Lahkola et al. (2007, 2008) or less than 1 year ago in Sadetzki et al. (2008)
