The NNT is a web site offering summaries of evidence of treatments and diagnostics. The difference with this site is the summaries use NNT - Number Needed to Treat, to assess the likely benefits or harms of a particular intervention.
NNT is "a measurement of the impact of a medicine or therapy by estimating the number of patients that need to be treated in order to have an impact on one person" There is a handy tutorial video, which you can see below that offers a clear explanation of the concept produced by the site.
Summaries of evidence are listed by speciality and system, as well as being fully searchable. They are based on evidence from Cochrane systematic reviews and published randomised controlled trials. The summaries are very clearly set out showing exactly how beneficial an intervention is based on NNT.
The site also features a blog which reviews the latest research trials as well as offering comment on the use of evidence in practice. There is a section which clearly explains how the NNT site methodology is used in producing the evidence summaries and a quiz which allows you to rate the effectiveness of interventions and compare it with the NNT rating.
