Does being a retired or employed caregiver affect the association between behaviours in Alzheimer’s disease and caregivers’ health-related quality-of-life?

Table 2 Regression analysis: caregiver health utility scores regressed on Dementia Behaviour Disturbance Scale score and caregiver employment status
