How are USPSTF recommendations graded?

• A. Gold, Silver, Bronze, Copper.
• B. A, B, C, D, or I based on the balance of benefits and harms and certainty.
• C. Pass/Fail with numeric score 0-100.
• D. Recommended/Not Recommended with levels mild/moderate/severe.

Answer: (B)

The main idea being tested is how USPSTF expresses its recommendations. USPSTF uses a graded system that reflects both the balance of benefits and harms for a service and how certain we are about that balance. This approach communicates not just whether a service is beneficial, but how strong that benefit is and how confident we can be in the estimate.

In this framework, a recommendation structure is used that signals different levels of benefit and certainty: the strongest endorsements come when there is substantial net benefit with high certainty; a robust but slightly less certain benefit leads to a strong but more moderate endorsement; a conditional endorsement suggests only a small or context-specific benefit; a recommendation against means harms likely exceed benefits; and an I statement indicates insufficient evidence to judge net benefit. This system is purpose-built to convey both the expected value to patients and the confidence behind that value.

The other options describe grading schemes that USPSTF does not use—such as metaphorical metal tiers, a numeric pass/fail score, or simple recommended/not recommended with descriptors like mild/moderate/severe—so they don’t fit how USPSTF grades recommendations.
