^aDAFS = Direct Assessment of Functional Status; IADL = instrumental activities of daily living. DAFS IADL theoretical range = 0–58, with higher scores representing higher functional status. Self-report/proxy report IADL theoretical range = 0–16, with higher scores representing higher functional status.
