TEP = thromboembolic phenomena; ICU = intensive care unit; APACHE II score = Acute Physiology and Chronic Health Evaluation II score; SOFA score = Sequential Organ Function Assessment score; DVT: deep vein thrombosis. Massive transfusion was defined as replacement of >1 blood volume in 24 hours or >50% of blood volume in 4 hours (adult blood volume is approximately 70 mL/kg).
