I want to find patients with a diagnosis of primary hypertension (NOS), diabetes mellitus (ICD10-ICD9 code e08-e13), and who have been prescribed insulin medication (LME150-LME152) at any time in their medical history. The specificity scale is set to 0, and the accuracy scale for each panel is set to 100, meaning that the search will be inclusive of all possible matches. The panel numbers represent different categories of data to be searched: the first panel is for the diagnosis of primary hypertension, the second panel is for the diagnosis of diabetes mellitus, and the third panel is for insulin medication. The hlevel values indicate the hierarchy level of the items within each panel, and the tooltips provide more detailed descriptions of the categories being searched. The class attribute is set to "ENC," which stands for "Encounter," indicating that the query is searching for encounters where these conditions or medications were documented. The item_is_synonym attribute is set to "false,"
