  1. Continuous data are presented as median (interquartile range), and their association with cholinesterase was assessed by using Spearman–Rho correlation coefficient. ECMO, extracorporeal membrane oxygenation; IABP, intraaortic balloon pump; GFR, glomerular filtration rate estimated by using Cockcroft-Gault formula; SAPS II, simplified acute physiology score II.
  2. Bold typefaces indicates statistical significance (P < 0.05).
