Figure 3. Effect of the Care Ecosystem on Total Cost of Care in Months 7 to 12 Postenrollment Among Patients With Dementia, Overall and Stratified by Patient and Caregiver Characteristics.

All models included a 3-way interaction term including the subgroup of interest, time period, and the intervention and excluded patients with a DFBETA value above 2/√N for either the 6- or 12-month Care Ecosystem effect. Models also adjusted for dementia severity as a continuous Quick Dementia Rating System score, except for the analysis that specifically examined the interaction between dementia severity and the Care Ecosystem treatment effect, in which case dementia severity was dichotomized and included in the 3-way interaction. ED indicates emergency department.
