Model for AChEI and memantine use with interaction terms for Black and Non-Black Hispanic with the other demographic variables. MMSE = Mini-Mental State Examination; CDRGLOB = Global Clinical Dementia Rating; AChEI = Acetylcholinesterase Inhibitor. Significant interactions are noted with grey background.
