Yeah, but that's a super-weird study. If you read the data tables in the actual study (https://academic.oup.com/aje/article/155/12/1096/123184?logi...) you see some weird conclusions like

* For adult men 8-10 km away, the radio station reduced cancer cases by 75%! Hooray! * It had slight benefits for the same group at 4-8 km * It caused a couple of extra cases at 0-4 km

But then you realize we're talking about drawing conclusions from an n=40 study... That's just not enough to draw meaningful conclusions. And for children, it was n=8 !!!!!
