The past two decades have seen a growing emphasis on basing healthcare decisions on the best available evidence. Professional organizations frequently use their own scales (e.g., American Heart Association, American College of Chest Physicians); publishing companies and evidence-based practice textbooks have developed their own scales, too (e.g., Elsevier, UpToDate). So we have less “confidence” in the results of lower level studies because we know there is more chance for error. If it meets your requirements, approve and download it. Randomized controlled trials (RCTs) are the strongest research designs for treatment or intervention studies because they exert the most control over the methods. Once we critically appraise a study, the quality of the evidence is graded according to an established scale or hierarchy. • Level II-1: Evidence obtained from well-designed controlled trials without randomization. More control means there is less of a chance of systematic or random error and therefore, the results are considered more trustworthy. Glasziou, P., Vandenbroucke, J., & Chalmers, I. What is a Levels of Evidence Scale and What Does it Tell You? The Integrated Pyramid also includes foundational resources that do not have transparent evidence-based methodologies.
