*
Plus-minus values are means plus or minus standard deviation. The Katz Activities of Daily Living (ADL) score and the Instrumental Activities of Daily Living (IADL) score are functional assessments based on a 12-point scale, with 0 representing total independence and 12 representing total dependence. Percentage may not sum to 100 because of rounding.
