  1. Data are presented as number (percentage), mean (± standard deviation) or median (interquartile range). Demographic data of studied patients. ALS, advanced life support; BLS, basic life support; CPR, cardiopulmonary resuscitation; EMS, emergency medical system; ROSC, return of spontaneous circulation.
