  1. CFB Cumulative fluid balance
  2. *Adjusted for age, sex, Charlson comorbidity index, Acute Physiology and Chronic Health Evaluation II score, and propensity score
  3. Propensity score was obtained by logistic regression analysis with covariables body mass index, extracorporeal membrane oxygenation (ECMO) pump time, ECMO blood flow rate, albumin, total carbon dioxide, acute kidney injury stage
  4. The 27 (3.7%) patients who were lost to follow-up were treated as censored
