Spellings are joined only when they reduce to the same name, or a reviewed source names the same company. Sharing an FDA establishment number (FEI) is not enough: contract sites make products for many firms. Facts marked AI were labelled by a language model from the firm's FDA names; everything else comes from FDA or Wikidata. How this page is built
