aAge and CPR duration are expressed as mean and standard deviation. aMissing data for seven patients; the survival rate was calculated assuming nonsurvival of these patients. For the respective variables, data are missing bfor 2 patients, cfor 1 patient, dfor 19 patients, efor 1 patient, ffor 4 patients, gfor 2 patients, and hfor 1 patient. “Initial rhythm shockable” denotes ventricular fibrillation or ventricular tachycardia; “initial rhythm not shockable” denotes either asystolia, pulseless electric activity, bradycardia, pacemaker, normal sinus rhythm, or other rhythm. “Presumed cardiac etiology” is classified as either myocardial infarction, arrhythmia, or other cardiac etiology as the suspected first diagnosis for the cause of arrest. “History of malignancy” denotes the diagnosis of any malignant tumor or disease during the respective hospitalization any time before cardiopulmonary resuscitation. “Recent history of surgery” denotes a surgical procedure during the respective hospitalization during a maximum of 28 days before cardiopulmonary resuscitation.
