Two models of risk estimates (odds ratios) for cognitive domains in CASI between the delusional and nondelusional patients with DLB.

DLB: dementia with Lewy bodies; CASI: Cognitive Abilities Screening Instrument; NS: not significant. The odds ratio (OR) and 95% confidence interval (CI) were calculated with the nondelusional group as reference. Model 1 ORs were adjusted for age, gender, and education; model 2 ORs were adjusted for age, gender, education, disease severity, antipsychotics, and antiparkinsonian agents.
