Dr. David Newman pulled together a small group of mostly young, reform-minded New York City emergency medicine docs to create and run this site. It currently reviews over a hundred therapies and wraps them up in the statistical bow of Number Needed to Treat, while providing handy links to the research from which the NNTs are generated, often Cochrane Collaboration meta-analyses.
How to Navigate:
- The site is a breeze to navigate: click on the “Reviews” drop-down menu, top-left on the home page, and open either “Therapy Reviews” or “Diagnosis Reviews.”
- Once you’re in, you can go to the large blue box at the top-left of the page, and organize the reviews alphabetically, or by body system or medical specialty.
- Each therapy review gets a colored banner on the top of the page indicating whether the therapy in question is of more benefit than harm (green); of unclear benefit (yellow); or of no benefit (red). You won’t find the fourth option on a stop light, black, of demonstrated harm (see PSA screening and coronary stenting for stable heart disease). If NNT numbers could shout, these would.
