Note: Variables included in the initial analysis but excluded from the final model (jointly not significantly different from zero at the 0.2 level): renal failure, hip fracture interacted with dementia.

^aAll variables are significant at the 0.001 level unless otherwise noted as follows:

^*Significant at the 0.05 level.

^**Significant at the 0.01 level.

^***Jointly significant at the 0.10 level.

^bOther assessments include significant change of status and significant correction to prior full assessments.

^cVariable was imputed from a prior full-information observation.

NA: In the quarterly assessments, these variables were not recorded and not inputed.

NS: Not significant at the 0.05 level.
