Data are presented as means ± SD or number (%).Hemorrhage was defined as a loss of 3 or more g/dl of Hb and/or the need for 3 or more PRBC units in fewer than 6 hours, together with a clinical source of bleeding. Iron supplementation is the use of any iron preparation (either intravenous or oral). ICU: intensive care unit; ID: iron deficiency; non-ID: no iron deficiency; PBRC: packed red blood cells; SAPS II: Simplified Acute Physiology Score II; SOFA: Sequential Organ Failure Assessment. Values in italic are p values.
