FIGURE 15. Predicted Risk of Mortality Derived From the Logistic Regression Model Without Center Case Volume as a Covariate.

FIGURE 15

Actual mortality and the ratio of actual mortality to predicted mortality (A/P ratio, the risk-adjusted mortality rate) are also shown. A similar predicted risk of mortality across the case volume strata and a decrease in the actual mortality at higher center case volume are seen.
