Note: Variables included in the initial analysis but excluded from the final model (jointly not significantly different from zero at the 0.2 level): cancer, viral hepatitis, syncope (fainting), burns, surgical wounds, infection of the foot, and chemotherapy.

a

Full-information assessments include admission, annual and change of status assessments

b

All risks factors were significant at the 0.001 level except for ventilator which was significant at the 0.05 level.

c

Indicates that these variables were imputed from a prior full information observation.

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

NS: Not significant at the 0.05 level.

COPD, chronic obstructive pulmonary disease.
