Figure 3.

Results reported by the meta-analysis by Kim et al. [11]. Risk ratios and 95% confidence intervals (CIs) were plotted in logarithmic scale. All outcomes, except for survival at discharge in out-of-hospital cardiac arrest (OHCA), favor extracorporeal cardiopulmonary resuscitation (ECPR), although there was a little in-study heterogeneity (red: IHCA, blue: OHCA). CCPR: conventional cardiopulmonary resuscitation; IHCA: in-hospital cardiac arrest; CPC: cerebral performance category; NA: not applicable.
