DynaMed Levels of Evidence
Quickly find and determine the quality of the evidence.
DynaMed provides easy-to-interpret Level of Evidence labels so users can quickly find and determine the quality of the best available evidence. Evidence may be labeled in one of three levels:
1Level 1 (likely reliable) Evidence
2Level 2 (mid-level) Evidence
3Level 3 (lacking direct) Evidence
Grades of Recommendation
Guideline producers are now frequently using classification approaches for their evidence and recommendations, and these classifications are recognized and requested by guideline users. When summarizing guideline recommendations for DynaMed users, the DynaMed Editors are using the guideline-specific classifications and providing guideline classification approach when this is done.
