The numbers do the talking..


They say:

We are a group of physicians that have developed a framework and rating system to evaluate therapies based on their patient-important benefits and harms as well as a system to evaluate diagnostics by patient sign, symptom, lab test or study.

We only use the highest quality, evidence-based studies (frequently, but not always Cochrane Reviews), and we accept no outside funding or advertisements.

We say:

A good resource. The site looks at Diagnostics, Therapies and Risk Assessments and presents findings with statistical references as well as links to source studies and papers.

Findings are grouped in three categories, namely:

  • Interventions That Work
  • Interventions That Don’t Work
  • Interventions That Need More Study

Within each category the various treatments or procedures studied/evaluated are listed.

The site covers a wide range of medical specialities.
