NNT is often defined as number needed to treat to prevent one *ADDITIONAL* adverse outcome (think psychosis prevention), which I always found weird. It would mean when NNT=4, I need to treat 5 people (treating 4 prevents additional outcome in 5th). HALP

noooooo, see this post I wrote on it. Jane Hutton has pretty much destroyed the NNT and there are countless of reasons to not use it as opposed to the ARR. Excuse the fact that I wrote this article half asleephttps://lesslikely.com/statistics/problems-with-nnt/ …

Best description imo is the ARR represented as differences in numbers out of 100 (or similar) Population rates of disease are a great example. Always in number per 100,000, very easy to understand for everyone!
