I want to find all diagnoses related to the circulatory system (ICD codes 390-459) within the i2b2 database, with a specificity scale of 0, a panel accuracy scale of 100, and a panel timing set to ANY. The query will be named "Circulatory sys@10:46:16" and the panel number will be 1, with the total number of items in the panel set to 1. The item will be classified as an ENC (Encounter) and will not be considered a synonym.
