The study recalibrated APACHE-IV using logistic regression with hospital death as the outcome. APACHE-IV recalibration was performed separately for CABG and non-CABG patients because different APACHE-IV models apply to those groups.

APACHE-IV case-mix adjustment remains imperfect because it lacks some domain-specific predictors and comorbidities.
