The above article shows that there could well be a relationship between power cables and childhood leukaemia, but that its not totally statistically significant. It does say. however that they're sure there is a link.
For diseases , I'm unsure what the word 'significant' actually means, certainly 95.6% but but could be up to 99%. Stats doesnt give a yes or no, just the chances of it being one or the other, 95% being the normal one for saying , YES .
However, this is not the first study on this subject and have read several over the years.
The problem when you are dealing with relatively rare incidents is getting the amount to be observed, which the above study sounded like it didn't.
In stats the more the merrier as the uncertainty drops.
So why not someone combine this and previous studies to get a definite but significant maybe ?
