Cox proportional hazard regression for pre-extracorporeal membrane oxygenation (ECMO) risk factors associated with 30-day mortality in patients with cardiogenic shock during ECMO support. SAVE, Survival After Venoarterial Extracorporeal Membrane Oxygenation; HCO₃-, bicarbonate; Hgb, hemoglobin; K, potassium; HR, hazard ratio; CI, confidence interval. **p<0.01.|@|~(^,^)~|@|Comparison of receiver operating characteristic (ROC) curves among albumin-related parameters for the prediction of 30-day mortality. The area under the ROC curve of albumin (pre- extracorporeal membrane oxygenation [ECMO]) levels was 0.73 (standard error [SE], 0.05; 95% confidence interval [CI], 0.63–0.81; p<0.001; cut-off value=3.4 g/dL). The area under the ROC curve of albumin (mean value within initial 48 hours of ECMO) levels was 0.62 (SE, 0.05; 95% CI, 0.53–0.71; p=0.02; cut-off value=3.1). The area under the ROC curve of albumin levels (mean value during intra-ECMO) was 0.62 (SE, 0.05; 95% CI, 0.53–0.71; p=0.021; cut-off value=3.2). The area under the ROC curve of the amount of albumin infused (adjusted levels) was 0.74 (SE, 0.05; 95% CI, 0.65–0.81; p<0.001; cut-off value=4.8).|@|~(^,^)~|@|Cumulative incidence of 30- day mortality from the time of extracorporeal membrane oxygenation (ECMO) initiation. Survival analysis with cumulative 30-day mortality incidence from the time of ECMO initiation. Patients with pre-ECMO albumin levels of less than 3.4 g/dL had a lower survival probability (p<0.001) than patients with pre- ECMO albumin levels of more than 3.4 g/dL.|@|~(^,^)~|@|Probability regression between albumin infusion and 30-day mortality. This figure showed a correspondence between the adjusted amount of albumin infused and the possibility of 30-day mortality. As the adjusted amount of albumin infused increased, the possibility of 30-day mortality also increased (coefficient=0.140; standard error, 0.037; p<0.001).
