I want to find patients with a diagnosis of Essential (primary) hypertension and Diabetes mellitus (e08-e13) within the specified timeframe (ANY). This query includes two panels, the first one focuses on diagnoses of diseases of the circulatory system (i0-i9) and specifically on essential (primary) hypertension (i10), while the second panel looks at endocrine, nutritional, and metabolic diseases (e0-e89) and specifically diabetes mellitus (e08-e13). The specificity scale is set to 0 and the accuracy scale is set to 100 for both panels, indicating that the query is highly specific and accurate. The invert parameter is set to 0, meaning that the results will not be inverted or negated.
