The first study:

> METHODS: A cohort of 10,051 male and 160 female airline pilots [...] was followed for cancer incidence [...].

> RESULTS: Among male pilots, there were 466 cases of cancer diagnosed vs. 456 expected.

So, a heightened risk of (466-456)/10051 = 0,001% if I read this correctly.

Or am I misunderstanding something here? I guess so, because this seems close to negligible.

You forgot to multiply by 100 when you went to %, so it's actually 0.1% higher. Still pretty low.

ah, thanks, silly mistake! Anyway, still a surprisingly low risk. Seems within the margin of error to me.
