Class I
Benefit >>> Risk
 
 
 
 
 
Procedure/treatment should be performed/administered Class IIa
Benefit >> Risk
Additional studies with focused objectives needed
 
 
 
It is reasonable to perform/administer treatment Class IIb
Benefit ≥  Risk
Additional studies with broad objectives needed; additional registry data would be helpful
 
Procedure/treatment may be considered Class III
Benefit ≥ Risk
No additional studies needed
 
 
 
Procedure/treatment should not be performed/administered since it is not helpful and may be harmful
Level A
 
Multiple (3-5) population risk strata evaluated  Recommendation that procedure or treatment is useful/effective
 Sufficient evidence from multiple randomized trials or non-randomized trials  Recommendation in favor of treatment or procedure being useful/effective
 Some conflicting evidence from multiple randomized trials or meta-analyses  Recommendation’s usefulness/efficacy less well established
 Greater conflicting evidence from multiple randomized trials or meta-analyses  Recommendation that procedure or treatment not useful/effective and may be harmful
 Sufficient evidence from multiple randomized trials or meta-analyses
Level B
 
Limited (2-3) population risk strata evaluated  Recommendation that procedure or treatment is useful/effective
 Limited evidence from single randomized trial or non-randomized studies
 Recommendation in favor of treatment or procedure being useful/effective
 Some conflicting evidence from single randomized trial or non-randomized studies  Recommendation’s usefulness/efficacy less well established
 Greater conflicting evidence from single randomized trial or non-randomized studies  Recommendation that procedure or treatment not useful/effective and may be harmful
 Limited evidence from single randomized trial or non-randomized studies
Level C
 
Very limited (1-2) population risk strata evaluated  Recommendation that procedure or treatment is useful/effective
Only experts opinion, case studies, or standard-of-care
 Recommendation in favor of treatment or procedure being useful/effective
 Only diverging expert opinion case studies, or standard-of-care  Recommendation’s usefulness/efficacy less well established
 Only diverging expert opinion case studies, or standard-of-care  Recommendation that procedure or treatment not useful/effective and may be harmful
 Only expert opinion case studies, or standard-of-care
