I want to find all female patients in the i2b2 database with a gender attribute value of "Female" and exclude male patients with a gender attribute value of "Male" from the search results. The query will have a specificity scale of 0 and an accuracy scale of 1000%. The time frame for the search is not restricted and can include any date or time. The query will return one item per panel, and the search will include two items: "Female" and "Male" from the "Demographics" category. The query will be represented in the "Encounter" class.
