Thank goodness I turn the wifi off before I go to sleep.

Seriously, a sample of 55 Japanese kids with tumours and fewer than 100 in the control group? Of those 55, just 3 were in areas estimated to have higher exposure than 0.4 μT?!

The discussion is largely an explanation of the study's substantial weaknesses, too. For instance:

"A limitation of this study is its small sample size, which resulted in a very wide confidence interval for the odds ratio in the highest exposure category, ie, above 0.4 μT. Although the odds ratio of 10.9 was statistically significant (the 95% confidence interval did not include unity), a shift of 1 case in the highest exposure category into a lower exposure level would have yielded a nonsignificant OR, markedly below 10.9."
