The NNT
Quick summaries of evidence-based medicine
[Price: free]
Background: There are lots of medical studies. Most are garbage. Certain people like to use certain statistics (like relative risk reduction *cough cough*) to exaggerate the positive benefits of a certain drug or intervention. This website lasers past that and looks at the cold hard numbers. The NNT refers to “number needed to treat,” which is the inverse of the absolute risk reduction. Go read about the statistics on another website for more info.

I appreciate the bold red or green bar and the quick summary boxes at the top and the wordy details below.
This is patient-friendly enough, it may be helpful to whip out during a patient encounter for shared-decision making.
