  1. ATC, acute traumatic coagulopathy defined as INR >1.2. MT, massive transfusion defined as 10 or more packed red blood cells. All AUCs values are statistically different from 0.5 with a P ≤0.001. *AUC is significantly larger than the AUC of the ROTEM parameters (P = 0.002 for difference to FIBTEM CA5). ROC, receiver operating characteristics; AUC, area under the curve; CT, clotting time; CA5, clot amplitude after 5 minutes; CA10, clot amplitude after 10 minutes; CFT, clot formation time; MCF, maximum clot firmness; INR, international normalized ratio.
