I want to find all patients with an admit diagnosis of any diseases of the circulatory system (ICD codes I0-I9) within the specified time frame. This query is designed to identify patients with any diagnosis related to diseases of the circulatory system, including conditions such as hypertension, ischemic heart disease, and cerebrovascular diseases, among others. The query will return results with 1000% accuracy and includes only one item in the panel. The specificity scale is set to 0, indicating that the query is not restricted to a particular level of specificity.
