Sources and editorial policy

How we present information

• Product identity comes from official manufacturer and catalogue documents.
• Findings come from the published study itself, with the tested product and comparator named.
• We state study size, follow-up and limitations beside the findings.
• We keep laboratory and animal research separate from results in people.
• We include published safety reports, including single case reports.
• Images are labelled: editorial photography is not a patient or treatment result, and diagrams are illustrations or data redraws.
