Start with the record that matches your question. Read it alongside the claim, then ask what it means for the care being offered.
Read the record in context
A law, agency guidance and a study answer different questions. Guidance explains a position; it is not automatically a rule binding every situation.
The medical boards’ advice about choosing a medicine from an online menu is guidance. It is not a law that applies across the country.
Keep the date with the claim when discussing it. Ask for help with a term that changes the meaning.
