Soon after the inception of the evidence-based medicine (EBM) movement in the 1990s, the evidence pyramid rose from the sand.1 As more evidence resources and resources for finding evidence were developed it became necessary to provide guidance on their use. The original '4S' system (systems (eg, computerised decision support), synopses, syntheses, studies) soon evolved into the '5S.

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. Allow me to be your guide as we tour.

A pyramid has expressed the idea of hierarchy of medical evidence for so long, that not all evidence is the same. Systematic reviews and meta-analyses have been placed at the top of this pyramid for several good reasons. However, there are several counterarguments to this placement. We suggest another way of looking at the evidence-based.
The Hierarchy of Evidence Applied Statistics in Healthcare Research
A hierarchy of evidence, comprising levels of evidence (LOEs), that is, evidence levels (ELs), is a heuristic used to rank the relative strength of results obtained from experimental research, especially medical research.There is broad agreement on the relative strength of large-scale, epidemiological studies.More than 80 different hierarchies have been proposed for assessing medical evidence.

Upon What Evidence Are 'EvidenceBased' Practices Based? — R1 Learning
The evidence-based medical literature is usually represented graphically as being arranged in a pyramid shape, the idea being that it is spread over several levels, with the higher ones, towards the top of the pyramid, being equated with higher standards and thus, implicitly, better quality evidence. In actual fact, this pyramid-shaped.
