Question Posted 12/08/17:
Dear Expert, for the key background medications file BACKMEDS under medical history, under the column KEYMED, why some values are like "4:05:06" but not one of the 7 specified medicine types? Is it a typo or how to interpret it? Thank you very much for your help.

When multiple values are chosen they are separated by a delimiter (either ":" or "|").
