I want to find all patients who have been prescribed antihyperlipidemic agents at any time, with a specificity scale of 0, accuracy scale of 100, and only one occurrence of the medication is required. This query is based on the "Antihyperlipidemic agents" panel in the i2b2 Medications domain, with the hlevel set to 2 and the icon set to FA. The query is not a synonym and is classified as an ENC (Encoded Concept) type.
