The rates are estimated from a marginal logistic regression model (PROC GENMOD). Odds ratios generated from the same model are also presented. Percentages may not sum to 100 due to rounding.
Estimated from a multilevel model with patient characteristics presented in the table, plus major diagnostic category and 31 Elixhauser comorbidity indicators entered individually.
Per 1 DRG unit, 1 hospitalization, or 10 physician visits.
Calculated at the median point for continuous variables.
