Abbreviations: ADL = Activities of Daily Living, CFS = Cognitive Function Scale, IQR = interquartile range, SMD = standardized mean difference
Standardized mean differences are calculated for the difference between the Development and Validation samples
Number of active conditions represents the sum of comorbidities noted in the active diagnosis checkbox on the Minimum Data Set within the previous year.
Physical function was measured using Activities of Daily Living (ADL) via the Minimum Data Set Morris 16-point ADL Short Form score. The ADL scores range from 0 to 16, with 0 indicating total independence and 16 indicating total dependence in all ADLs.
Obtained from question B1000. Vision on the Minimum Data Set version 3.0. Visual impairment recorded as any value other than “Adequate”.
