Evidence Pyramid for Studies

This pyramid illustrates the levels of evidence strength for different types of studies, found in databases like CINAHL and MEDLINE. Evidence strength decreases as you move down the pyramid, while at the same time the number of articles increases. As you can see, Systematic Reviews are at the top of this pyramid, because they provide the strongest evidence by pooling the evidence from many individual studies.
