Research documentation
Methodology
How we assess sources
Source types depend on the claim. We prioritize regulatory records, trial publications and registries, and use official pricing pages, company filings, medical-society guidance, and reputable secondary reporting where relevant. Company announcements are not treated as independent confirmation.
01
Source Identification
FDA labels, published studies, trial registries, official pricing and company records, and relevant professional guidance.
02
Cross-Referencing
We compare claims with independent sources when available and appropriate. Some facts, such as listed prices or exact label wording, are best verified against the issuing source; not every claim has two independent sources.
03
Ongoing Verification
Pricing and availability data re-verified on a monthly cycle.
