  1. +Note n represents number of patients in the cohort receiving the particular fluid i.e., 73 patients in the calcium-free cohort received 0.45 % saline
  2. aCalcium-free balanced crystalloid (e.g., Plasma-Lyte or Normosol: Na 140 mmol/L, Cl 98 mmol/L, K 5.0 mmol/L, Mg 1.5 mmol/L, gluconate 23 mmol/L, acetate 27 mmol/L)
  3. bMonitored fluids (calcium-free balanced, 0.45 % saline, lactated Ringer’s, 0.9 % saline)
