The bar chart of prevalence of disability in terms of dementia stage scales.
The prevalence of disability is shown at the top of each bar chart. CDR; The Clinical Dementia Rating, FAST; Functional Assessment Staging Test, GDS; Global Deterioration Scale.

Regression analysis showing the association of IADL scores (dependent variable) with the dementia staging scales, cognitive and behavioral scales (independent variable, separated model for them) (n = 871).
Fig 3.
Prevalence of neuropsychiatric symptoms in terms of disability.
Neuropsychiatric symptoms were more common in dementia patients with disabilities than in those without disabilities. Significant difference between groups; **p < 0.001, * p < 0.05.
