I want to find all patients with any diagnosis of cerebrovascular disease in the i2b2 database using the query builder. The query will search for diagnoses in the Circulatory system category, specifically within the Cerebrovascular disease subcategory (codes 430-438). The specificity scale is set to 0, meaning that any mention of the condition will be included, and the accuracy scale is set to 100, indicating high confidence in the results. The panel timing is set to ANY, so the query will return results regardless of when the diagnosis was made. The total number of items in the panel is 1, and the class of the item is ENC (encounter). The query will not be inverted, and there is only one occurrence of the item in the panel. The query is named "Cerebrovascular@1:13:13."
