analysis of mobile phone use

Sir,
Since I would imagine the lending of mobile phones to be unusual, I wonder

if the authors have overlooked a glaring objective measure of telephone
exposure. Cellular phone companies can give very accurate accounts of time

used. Even considering other factors such as hands-free equipment, why was

this not analysed? Doubtless the companies would have been keen to assist
if, as seems likely, their product would have been given the all clear.
