01Motivation
AI medical citations: can we trust them?
- When a medical AI cites, one question decides trust: does the cited article really support the statement?
- Existing systems answer without citations, or attach references that may not back the claim.

02Method
End-to-end citation generation and evaluation
- A citation seeker re-retrieves and reranks the sources behind each generated statement.
- An attribution judge then checks whether each cited article actually supports its claim.

Grounding the answer lifts citation quality
| Method | Accuracy | MAUVE | ROUGE-L | Cite recall | Cite prec. |
|---|---|---|---|---|---|
| Non-RAG | 71.4 | 53.2 | 18.1 | 59.1 | 52.9 |
| RAG | 82.9 | 52.2 | 14.8 | 49.0 | 42.8 |
| RAG w. Oracle | 94.3 | 63.5 | 20.6 | 57.5 | 43.2 |
Grounding the answer in retrieved evidence (and an oracle upper bound) raises answer quality. Source: Table 2.

Re-retrieval with LLM reranking wins
| Citation-seeking strategy | Cite recall | Cite prec. |
|---|---|---|
| Pre-gen shortlist + LLM rerank | 54.7 | 41.4 |
| Retriever-only re-retrieval | 65.7 | 47.7 |
| Re-retrieval + NLI rerank | 65.4 | 55.1 |
| Re-retrieval + LLM rerank | 65.8 | 61.0 |
Citation quality by attribution strategy (answer accuracy 83.3 for all). Re-retrieval + LLM reranking gives the best precision. Source: Table 3.

The multi-pass method beats single-pass
| Configuration | Accuracy | MAUVE | ROUGE-L | Cite recall | Cite prec. |
|---|---|---|---|---|---|
| Non-parametric (single-pass) | 82.9 | 52.2 | 14.8 | 49.0 | 42.8 |
| Hybrid (multi-pass) | 83.3 | 59.2 | 16.8 | 65.7 | 47.7 |
The multi-pass hybrid design lifts citation recall and precision at comparable answer quality. Source: Table 4.
