I want to find patients who have been diagnosed with Hyperlipidemia within the specified time frame, along with their medication history related to HMG-CoA reductase inhibitors, which are a class of antihyperlipidemic agents. The specificity scale is set to 0, meaning the query will return all possible matches, and the panel timing is set to ANY, indicating that the query is not limited to a specific time frame. The accuracy scale is set to 100, indicating a high level of accuracy, and the total number of items included in the query is one. The first item in the panel refers to a previous query called "Hyperlipidemia@18:00:06," while the second item focuses on the medication class of HMG-CoA reductase inhibitors. The invert value is set to 0, meaning that the items will be included in the query results.
