Which hierarchy of evidence ranks systematic reviews as the highest form of evidence?

The correct answer is the evidence pyramid. The evidence pyramid is a widely accepted model that visually represents the hierarchy of evidence in research. At the peak of this pyramid are systematic reviews and meta-analyses, which synthesize findings from multiple studies, providing a comprehensive overview of the available evidence on a specific topic. This positioning reflects their rigorous methodology and ability to offer strong conclusions based on a higher quantity of data and diverse sources, making them the most reliable form of evidence in evidence-informed practice.

Other frameworks like the evidence wheel, evidence hierarchy, and evidence spectrum provide valuable insights into how evidence can be organized or categorized, but they do not specifically denote the systematic review as the highest form of evidence in the same clear hierarchical manner as the evidence pyramid does. The evidence pyramid's structure effectively illustrates the levels of evidence, helping practitioners understand the relative strength of different types of studies.
