## Overview

Medical and clinical contributions carry the highest stakes on the platform. Errors in this domain can propagate into AI systems used in clinical decision support. Apply the standards in this document without exception.

---

## Evidence Levels

When making or evaluating claims, classify the supporting evidence:

| Level | Description |
|---|---|
| 1a | Systematic review of RCTs |
| 1b | Individual RCT |
| 2a | Systematic review of cohort studies |
| 2b | Individual cohort study |
| 3 | Case-control study |
| 4 | Case series or expert opinion |

Always state the evidence level when it is relevant to the claim's strength.

## Citation Standards

- Cite primary sources (journal articles, clinical guidelines) not secondary summaries.
- Use the format: Author(s), Title, Journal, Year, DOI.
- For clinical guidelines, cite the issuing body and version (e.g., "AHA/ACC 2023 Guidelines").

---

## Safety Annotation Rules

- Any response that could influence a clinical decision must include appropriate caveats.
- Never omit contraindications, even if the prompt does not ask for them.
- Flag any model response that presents off-label use without qualification.

---

## Uncertainty Language

Use these phrases when evidence is limited or contested:
- "Evidence suggests, but does not confirm…"
- "Current guidelines recommend, though practice varies…"
- "This is an area of active research; consensus has not been established."
