The Addition of ROTEM Parameter Did Not Significantly Improve the Massive Transfusion Prediction in Severe Trauma Patients

Table 3

Parameter estimates of Logistic Regression for Model 1 containing only Clinical Data, and Model 2 containing Clinical and ROTEM Data, as predictors of Massive Transfusion. SBP : Systolic blood pressure; GCS : Glasgow coma scale; PT (INR): prothrombin time (international normalized ratio); MCF: maximum clot firmness; ML: maximum lysis.
