Figure 4

Association between the level of prehospital management and survival to discharge according to scene time. The restricted cubic spline curve shows an adjusted association between the level of prehospital management (BLS only (navy), BLS + advanced airway (green), and BLS + advanced airway + epinephrine (red)) and the predicted probability of survival to discharge according to scene time. The shaded area indicates the 95% confidence interval of the predicted probability. The model was adjusted for sex, age, witnessed status, location of cardiac arrest, bystander CPR, initial cardiac arrest rhythm, prehospital defibrillation, response time, scene time, transport time, and prehospital ROSC. CPR, cardiopulmonary resuscitation; ROSC, return of spontaneous circulation.
