I want to find all patients with a diagnosis of very mild dementia or moderate dementia, as well as those who are nondemented, within any timeframe, using the Clinical Dementia Rating (CDR) and the Mini-Mental State Examination (MMSE) score in the OASIS clinical measures. The specificity scale is set to 0, and the panel accuracy scale is set to 100. The panel timing is set to ANY, and the invert option is set to 0. This query consists of two panels, each with a total of one item occurrence. In the first panel, there are two items related to dementia, and in the second panel, there is one item related to nondemented patients. The class for all items is ENC, and none of the items are marked as synonyms.
