Table 8.
Posterior summaries (medians and 95% credible intervals (CI)) for hazard ratio (HR) parameters for readmission, exp(β1), from semi-competing risks data analyses and odds ratios (OR) based on a LN-GLMM. For the latter, results are reported for models for which a semi-Markov specification was adopted for h03(·)
