NHD Technical Team maintains research-use catalog documentation and evidence summaries. Reviewed articles link to peer-reviewed papers, trial registries and regulatory records, retain null findings and study limitations, and distinguish published interventions from catalog materials. AI-assisted drafting may be used for structure; source links and evidence boundaries remain visible. This work is not independent peer review or medical advice.
