Figure 4: Functional outcome measures at baseline and during the follow-up assessments.

(A) Mini-mental state examination (MMSE). (B) A subscale of the multidimensional observation scale for elderly subjects (MOSES) for withdrawn behavior. (C) Cornell Scale for Depression in Dementia (CSDD). (D) Negative affect scale of the Philadelphia Geriatric Centre Affect Rating Scale (PGCARS). Data during the follow-up assessments were divided into three bins for better visualization (<6 months, 6–12 months, and >12 months). P values were obtained using mixed models in which time into the study was included as a continuous variable and subject as a random factor for intercept. Mean values were obtained from all individuals and error bars indicate standard errors (between individuals).
