  2. 1. * p< .05 **p< .01 ***p<.001.
  3. 2. Statistics reported in parens reflect robust 95% Confidence intervals for odds ratio and standard errors for beta coefficients.
  4. 3. Total hospitalizations and hospital lengths of stay were modeled with the subset of patients who experienced any hospitalization (n= 655).
  5. 4. Results from a restricted model using DCG comorbidity adjustment are shown here. Models that included individual comorbidity indicators yielded similar results.
