I want to find patients with a diagnosis of Diabetes Mellitus, using the i2b2 query builder with the specificity scale set to 0, panel accuracy scale set to 100, and the panel timing set to ANY, with the condition being part of the Endocrine disorders category under Other endocrine gland diseases, with the item key being \i2b2_DIAG\i2b2\Diagnoses\Endocrine disorders (240-259)\Other endocrine gland diseases (250-259)\(250) Diabetes mellitus\.
