In other words, the headline rounds UP from 83% to a 100% increase (double), but in actual fact it's more likely that the risk is somewhere around 75% instead!

It's also really hard to tell if the study used risks or odds unless you actually read it, which adds a layer of complexity to the matter

Honestly, I want to end on a nice easy note, but the fact is that odds are confusing, a lot of researchers get them wrong, and it's unlikely we'll have a solution to this any time soon Hurray!

Anyway, a reasonable proportions of the headlines you've seen probably overestimate the actual risk because the studies used odds ratios
