Evidence Based Medicine

Evidence based medicine (EBM) addresses the question ... "What is the evidence we have to justify the treatments used in clinical practice?". See here for a fuller description of 'levels of evidence'.

Clinical trials and other types of research aim to provide evidence ("proof") whether a particular treatment works, how well it works compared to other treatments, and what are the risks of the treatment. Various organisations collate the results of clinical trials and other research to determine the evidence for various treatments and procedures.

Main sources of reviews of EBM that are often used by health professionals include:
