Adjusted Results from Logistic Regression Models: Comparison of the Odds of Being Prolonged or Readmitted across Hospital Type, Location, and State^*

	Odds Ratio for Being Prolonged		Odds Ratio for Being Readmitted
Items for Comparison	Ratio	P-Value	Ratio	P-Value
New York vs. Pennsylvania:
NY City children's vs. Pittsburgh/Philadelphia children's	1.27	<0.0001	3.38	<0.0001
NY City general vs. Pittsburgh/Philadelphia general	1.64	<0.0001	2.33	<0.0001
Outside NY general vs. outside Pittsburgh/Philadelphia general	1.20	<0.0001	2.38	<0.0001
Children's vs. General:
NY City children's vs. NY City general	0.86	<0.0001	1.04	0.63
Pittsburgh/Philadelphia children's vs. Pittsburgh/Philadelphia general	1.12	0.26	0.72	0.33

^*The odds that a child will stay beyond three days or be readmitted after discharge are compared for several groups of hospitals. For instance, in the first row, a child in a New York City children's hospital is 3.38 times more likely to be readmitted after discharge than a similar child in a Pittsburgh or Philadelphia children's hospital. Stays beyond three days and readmissions are much more common in New York. Odds ratios are adjusted for covariates using a logit regression model.
