Classification of Recommendations and Level of Evidence

Classification of Recommendations:

“

Class I: Benefit >>> Risk Conditions for which there is evidence and/or general agreement that a given procedure or treatment is beneficial, useful, and effective. Class II: Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment. Class IIa: Benefit >> Risk Weight of evidence/opinion is in favor of usefulness/efficacy. Class IIb: Benefit ≥ Risk Usefulness/efficacy is less well established by evidence/opinion. Class III: Risk ≥ Benefit Conditions for which there is evidence and/or general agreement that a procedure/treatment is not useful/effective and in some cases may be harmful.

”

Level of Evidence:

“

Level of Evidence A: Data derived from multiple randomized clinical trials or meta-analyses. Level of Evidence B: Data derived from a single randomized trial, or nonrandomized studies. Level of Evidence C: Only consensus opinion of experts,case studies, or standard-of-care.
