I want to find patients with diagnoses related to Endocrine disorders and Other endocrine gland diseases (hierarchy level 3) as the primary diagnosis and those with diagnoses related to the Digestive system as the secondary diagnosis. The query has a specificity scale of 0, which means it is not specific to any particular time period, and the accuracy scale is set to 10, indicating high accuracy. The query is designed to return patients with both diagnoses in any time frame.
