Evidence Based Medicine (EBM) Pyramid
Levels of Evidence
The levels of evidence pyramid is a way to visualise both the quality of evidence and the amount of evidence available.
For example, systematic reviews are at the top of the pyramid, meaning they are both the highest level of evidence and the least common. As you go down the pyramid, the amount of evidence will increase as the quality of the evidence decreases.

Cochrane Database of Systematic Reviews (CDSR)
Supervised by a Cochrane Review Group (editorial team), Cochrane Reviews attempts to identify, appraise and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a specific research question. Researchers conducting systematic reviews use explicit, systematic methods that are selected with a view aimed at minimizing bias, to produce more reliable findings to inform decision-making. They are updated to reflect the findings of new evidence when it becomes available because the results of new studies can change the conclusions of a review. Cochrane Reviews are therefore valuable sources of information for those receiving and providing care, as well as for decision-makers and researchers.
