|Level of Value|
|High value: better outcomes at lower cost or ICER <$50,000 per QALY gained|
|Intermediate value: $50,000 to <$150,000 per QALY gained|
|Low value: ≥$150,000 per QALY gained|
|Uncertain value: value examined but data are insufficient to draw a conclusion because of no studies, low-quality studies, conflicting studies, or prior studies that are no longer relevant|
|Not assessed: value not assessed by the writing committee|
Proposed abbreviations for each value recommendation:
