Figure 3.

Three-year mean outcomes for the amount of HHS per week, with 95% confidence intervals, predicted with a multiple linear regression model according to different percentages of the maximum recommended ChEI dose (100% versus the mean 65% observed in this study).

Notes: Patients taking higher doses received lower volumes of HHS (P = 0.030). The arbitrary example presented in the figure is based on an average solitary-living woman with an MMSE score of 21, an IADL score of 17, and a PSMS score of 8 at the assessments and who was taking three medications at baseline.

Abbreviations: ChEI, cholinesterase inhibitor; HHS, home help services; IADL, Instrumental Activities of Daily Living scale; MMSE, Mini-Mental State Examination; PSMS, Physical Self-Maintenance Scale.
