I want to find all diagnoses recorded in the i2b2 database, with no specificity scale applied, and with 1000% accuracy, within any timeframe. This query will search for the Diagnoses concept in the i2b2_DIAG namespace, using the ENC (Encounter) class, and it will return one occurrence of the concept per patient. The query will not be inverted, and the panel number is set to 1.
