Table 9.

Posterior summaries (medians (PM) and 95% credible intervals (CI)) for standard deviations (SD) of the underlying population distributions for the patient-specific frailties and hospital-specific random effects. Estimates of population correlation components, between hospital-specific random effects, are also provided.
