Claim 84 · rag-reliability · finding
Liu et al. 2025's systematic review and meta-analysis of 20 biomedical studies found that retrieval-augmented generation produces a statistically significant, though modest, performance improvement over baseline LLMs, with a pooled odds ratio of 1.35.
Supported
E13 states the systematic review/meta-analysis included 20 studies and found a statistically significant effect (P=.001) with a pooled odds ratio of 1.35 (CI 1.19–1.53) for RAG over baseline LLMs, and the reported effect size directly supports characterizing the improvement as modest.
