I want to find all patients with a diagnosis of rheumatic fever without mention of heart involvement at any time, using the ICD-9 code 390 in the Circulatory System section of the Diagnoses category. The specificity scale is set to 0, indicating that the query will return all possible matches, and the accuracy scale is set to 100, meaning that the results will be highly accurate. This query is part of a panel with panel number 1, and the timing is set to ANY, meaning it can be applied to any time frame. The panel's accuracy scale is also set to 100, and the total number of items in the panel is 1. The icon for this item is LA, and the class is ENC. The query is not a synonym.
