Hello, I am with a medical publishing company in the United States. We are investigating enhancing certain collections of documents we produce with DC data. The individual documents describe disorders and treatment methods. Is there a guideline or standard that might assist us in selecting values that would be in alignment with comparable DC data for documents of this type? Thank you in advance.
