Figure S1. Flow diagram for selection of patients. Figure S2. Number of patients according to the year of extracorporeal membrane oxygenation treatment. Figure S3. Study flow chart for all of the included patients. Figure S4. Mortality and number of cases according to days on extracorporeal membrane oxygenation. Figure S5. (A) Observed mortality in derivation cohort according to pre-ECMO REMEMBER score quartiles (B) Predicted mortality in derivation cohort according to pre-ECMO REMEMBER score quartiles. N = number of patients in the study who had particular REMEMBER score. Figure S6. The areas under the receiver operating characteristic curves for predicting in-hospital death between early period (2004–2012) and late period (2013–2017). Table S1. Outcomes according to hospital survival status. Table S2. Pre-ECMO candidate variables associated with hospital mortality by univariate analysis. Table S3. Clinical characteristics of the patients at ECMO initiation. Table S4. Transformation of continuous variables into categorical variables. Table S5. Results of bootstrapping. Table S6.
