Multivariable models are adjusted for age, sex, Charlson Comorbidity Index, APACHE IV predicted mortality, and admission diagnosis of cardiac arrest. The SCAI Shock Classification was analyzed as a continuous variable to generate the unit OR value per each higher SCAI shock stage. APACHE indicates Acute Physiology and Chronic Health Evaluation; AUC, area under the receiver operating characteristic curve; OR, odds ratio; and SCAI, Society for Cardiovascular Angiography and Interventions.
