  1. The data are presented as median (interquartile range) or number (percentage). We conducted the Chi-square tests or Fisher’s exact tests for categorical variables and Mann–Whitney U tests for non-normally distributed continuous variables.
  2. CI: cognitive impairment; AMI: acute myocardial infarction; CHF: congestive heart failure; HTN: hypertension; DM: diabetes mellitus; VF: ventricular fibrillation; VT: ventricular tachycardia; PEA: pulseless electrical activity; ED: emergency department; CPR: cardiopulmonary resuscitation; MD: mood disorders; ICU: intensive care unit; LOS: length of stay.
