Level of evidence scales are rating scales. They provide a rating of the strength of the evidence, ranging from a summary to a manufacturer’s recommendation. The higher the evidence is in the hierarchy, the stronger the evidence. How the strength of the evidence is judged varies among the rating scales. Strength may be identified according to the type of study design and may also consider how rigorous the research methodology was in relation to the type of study design and/or the results of the study. The strength of the evidence is usually designated with numbers (e.g., Level 1,2,3 or
Level I, II, III) or qualifiers of study quality such as “high” or “low.” Some LOE scales use letter grades (e.g., Level A, B, C). Levels of evidence are assigned to studies based on the methodological quality of their design, validity, and applicability to patient care. These decisions give the "grade (or strength) of recommendation. The systematic review or meta-analysis of randomized controlled trials (RCTs) and evidence-based practice guidelines are the strongest level of evidence on which to guide practice decisions. (Melnyk & Fineout-Overholt, 2015) The weakest level of evidence is the opinion from authorities and/or reports of expert committees.Levels of evidence from one or more studies provide the grade (or strength) of recommendation for a treatment, test, or practice. Levels of evidence are reported for studies published in some medical and nursing journals. They are most visible in Practice Guidelines, where the level of evidence is usedto indicate how strong a recommendation for a practice is. This allows health care professionals to quickly ascertain the weight or importance of the recommendation in any given guideline (Fineout-Overholt & Johnston, 2005).Fineout-Overholt, E., & Johnston, L.
