This table summarizes the relation between mortality and APACHE II score, MI, and each of the three types of advanced life support at any time during the ICU stay (mechanical ventilation: 61.7% of patients; inotropes or vasopressors: 38.3% of patients; hemodialysis: 18.3% of patients). APACHE, Acute Physiology and Chronic Health Evaluation; CI, confidence interval; ICU, intensive care unit; MI, myocardial infarction; OR, odds ratio.
