What is the evidence based pyramid?
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 are the limitations of hierarchies of evidence?
Determining best evidence A limitation of current hierarchies is that most focus solely on effectiveness. Effectiveness is concerned with whether an intervention works as intended. While this is obviously vital, the scope of any evaluation should be broader.
Which type of evidence is considered to occupy the highest position?
The reason that studies are placed into a hierarchy is that those at the top are considered the “best evidence”. In the case of therapeutic trials this is the randomized controlled trial (RCT) and meta-analyses of RCTs. RCTs have within them, by the nature of randomization, an ability to help control bias.
