What is the Class of Recommendation and Level of Evidence assigned by the GWC?
The Class of Recommendation (COR) is assigned by the GWC and is the strength the GWC assigns to the recommendation, which encompasses the anticipated magnitude and judged certainty of benefit in proportion to risk. The Level of Evidence (LOE) rates the scientific evidence supporting the effect of the intervention on the basis on the type, quality, quantity, and consistency of data from clinical trials and other reports.
