With 44 people in the study it is not a large scale study.

Thanks for the link. However, it doesn't claim to be a large scale study just one of the largest ever completed.
I read the total participants as 158 not 44 but still not a significant number.
Interesting read but no surprises; useful fodder for the journos to pick up on. (watch this space)

University of Essex tested 44 people who had previously reported symptoms or sensitivity to mobile phone technology, and 114 people who had not reported any health effects (controls).

Unfortunately, controls don't count. It's the number of cases that is important.

Well, that's a surprise. Not.
When tested and not told that the gear was not actually transmitting, the sensitive souls got it wrong and still had headaches etc.
Whoopee.
And it isn't the biggest test either, nor particularly well done.

Not sure it is correct to say "the number of controls don't count"

I am not an epidemiologist but know sufficient to understand that if one is carrying out a study involving a possible source of harm then you have to have matched groups of people. Some who are exhibiting the ill effects due to exposure and a matched control group who are not. And matching implies for age, sex,etc and other exposures to possible sources of harm etc. It is only by matching subjects that other possible sources of harm can be ruled out.
