  1. AD Alzheimer’s disease, ADL activities of daily living, ER emergency room, HCRU health care resource use, iADL instrumental ADL, ZBI Zarit Burden Interview
  2. aData are presented as mean (SD) or median (Q1–Q3), unless indicated otherwise. Percentages reported are for caregivers with data available for each specific variable. Missing data for the total AD dementia population (overall diabetes status) were n = 1 for all measures (for caregivers and patients) except ZBI score (n = 9). 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)
  3. bDiabetes status was unknown for one caregiver, thus N = 1494
