AD Alzheimer’s disease, ADL activities of daily living, ER emergency room, HCRU health care resource use, iADL instrumental ADL, Q quartile, SD standard deviation, ZBI Zarit Burden Interview
Percentages reported are for caregivers and patients with data available for each specific variable. Missing data for the total AD dementia population (overall diabetes status) were n = 2 for all measures (for caregivers and patients) except ZBI score (n = 10). Missing data based on the population with mild/moderate AD dementia were n = 1 for all measures (for caregivers and patients) except ZBI score (n = 7)
