The Integrated "5S" Levels of Organization of Evidence Pyramid depicts the relationship between the Evidence Hierarchy (the small, inset pyramid) and the "5S" model. Levels of evidence (sometimes called hierarchy of evidence) are assigned to studies based on the methodological quality of their design, validity, and applicability to patient care.
