The pyramid is meant to assist researchers in prioritizing studies they have located to answer a clinical or practice question. This means that each choice of single or combined methods has to be based on the research question that needs to be answered and a critical assessment with regard to whether or to what extent the chosen method can accomplish this – i.e. Epub 2020 Aug 21. This was a qualitative meta-synthesis of select nursing research text books from 2001 to 2017 examining their discussions related to the Hierarchy of Research Evidence Models. The pyramid includes both qualitative and quantitative paradigms.

A hierarchy of evidence for assessing qualitative health research Pyramids vary slightly from source to source which can be confusing. The pyramid below represents the hierarchy of evidence, which illustrates the strength of study types; the higher the study type on the pyramid, the more likely it is that the research is valid. INTRODUCTION The nursing research pyramid, or nursing research hierarchy of evidence, provides a visual and systematic depiction of forms of research from the least reliable (base) to the most reliable (apex). A hierarchy of evidence-for-practice specific to qualitative methods provides a useful guide for the critical appraisal of papers using these methods and for defining the strength of evidence as a basis for decision making and policy generation.
