Outcome	Rehospitalized			Pressure sore(s)
Observations used	950:Yes = 343, No = 607			936:Yes = 128, No = 808

*All patient and treatment variables listed in Tables 1 and 2 were allowed to enter the models. Only statistically significant predictors are reported here; a missing variable name means that the variable did not predict any of the outcomes in this table; a blank cell means that the variable was not a significant predictor for the outcome examined.
