I want to find all instances of diagnosed cases of Diabetes Mellitus in the Endocrine disorders category, specifically under the subcategory of Other endocrine gland diseases, within the specified time frame (ANY). The query has a specificity scale of 0 and an accuracy scale of 100, indicating a high level of accuracy for the search results. The panel number is 1, and the panel timing is also set to ANY, meaning the search will be performed across all time periods. The query is not inverted, and only one item is included in the search. The item is located at the fourth hierarchical level (hlevel=4) and is identified by the key \i2b2_DIAG\i2b2\Diagnoses\Endocrine disorders (24-259)\Other endocrine gland diseases (250-259)\(250) Diabetes mellitus. The class of the item is ENC, and it is not a synonym.
