I've been meaning to do this since I created @justsaysrisks - new blog explaining relative vs absolute risk, and why they are both importanthttps://link.medium.com/ZqGVCYaLrX

Two big take-homes from this blog: 1. Most media stories use only relative risk, and this is a big problem 2. Journalists should be reporting both, because they are both important

If only one risk is going to be reported, I think that absolute risk difference is much more useful for actual people who are trying to interpret the figures

That being said, relative risk is extremely important for researchers like me who need to know the ratio of risks across different populations

As a researcher totally understand the value of ratio measures. Of late I am starting to believe that in terms of communicating results population attributable risks might be better. Thoughts?

I think that the PAF can be a very useful tool in communication but I don't think it applies to most media reports, so absolute risk difference is often more useful. But yes it is definitely helpful when used correctly

Yes, I was meaning absolute risk different (i.e population attributable risk) rather than PAF which is problematic as a factor can have a high PAF even when numbers are small. I see part of the solution is getting researchers themselves to talk in PAR rather than ratios

Ah yes apologies, I misread that. I agree that would help immeasurably, as well as press releases including PAR by default

No worries the PAF and PAR get muddled for me frequently despite teaching them for over 10 years now
