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, accuracy scale of 100, and the query timing set to ANY. This query is part of a panel with panel number 1, with the panel timing also set to ANY, and the total number of items in the panel being 1. The query is not inverted and the class is ENC.
