How we evaluate information
We prioritize primary sources and official data, and we make provenance explicit: peer-reviewed literature, registry reports, government guidance, and academic reviews inform our summaries. For transparency we cite authoritative sources directly in the text where they substantiate procedural or legal claims; for example, we link to context about evidence standards used by public health bodies.
We also maintain clear distinctions between summary, interpretation, and uncertainty so readers can see the difference between documented findings and open questions.
