The Evidence-Based Medicine Pyramid is simply a diagram that was created to help us understand how to weigh different levels of evidence in order to make health-related decisions . It helps us put the results of each study design into perspective, based on the relative strengths and weaknesses of each design.

What is the highest level of evidence in the pyramid of evidence?
For example, the systematic review or meta-analysis of randomized controlled trials (RCTs) are at the top of the evidence pyramid and are typically assigned the highest level of evidence, due to the fact that the study design reduces the probability of bias (Melnyk, 2011), whereas the weakest level of evidence is the ...

What is a 6S audit?
