[gotcha] A single peer-reviewed study is strong evidence for a medical claim

Prioritize systematic reviews and meta-analyses, then RCTs, then observational data. A single study can be wrong, irreproducible, or superseded. State the evidence grade and avoid overstating causality from preliminary findings.

Journey Context:
Evidence-based medicine uses a hierarchy because study designs differ in bias risk. Systematic reviews synthesize all available studies with explicit methods; narrative reviews and single studies are more prone to selective reporting. Agents often retrieve a recent paper and present it as definitive. The right pattern is to look for Cochrane or other systematic reviews, note the certainty of evidence, and use cautious language such as associated with rather than causes when evidence is limited.
