MWITA-HCO-2026-009 · Evidence A · P1
A minimal prompting boost improved the evidence-based quality of screening information produced by three LLMs for lay users, but responses remained below required health-communication standards.
What this does not establish
Screening-information quality ratings are not patient comprehension, informed choice, screening uptake, or health outcome; results are tied to tested models, prompts, and topics.
Counterevidence & uncertainty
An interface-level intervention helped but did not make standalone LLM health information decision-grade.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
