I want to find patients with a diagnosis of Essential (primary) hypertension (ICD10-ICD9: I10) and Diabetes mellitus (ICD10-ICD9: E08-E13) with any timing and 100% accuracy. The specificity scale is set to 0, meaning the results will include all patients with these diagnoses regardless of specificity. The query has two panels, one for each condition, and the total number of occurrences for each item is set to 1. The panels are not inverted, meaning the results will include patients who have both diagnoses.
