I want to find patients who have been diagnosed with diabetes (Essen-Diabe-Outpa@13:33:04) and have also been prescribed insulin (Insulin) at any time (ANY). The specificity scale is set to 0, meaning the results will include all possible matches, and the accuracy scale is set to 100, indicating a high level of confidence in the results. The panel number for the diabetes diagnosis is 1, while the panel number for insulin prescription is 2. The total number of items in both panels is 1, and the invert flag is set to 0, meaning the query is not inverted. The hierarchy level for the diabetes diagnosis is 0, while the hierarchy level for insulin prescription is 4. The icon for insulin is FA, and the class is ENC.
