Fig. 3From: Shock index in patients with traumatic solid organ injury as a predictor of massive blood transfusion protocol activationROC curves for different shock index (SI) cut-offs for prediction of blood transfusion in solid organ injury. Area under the Curve (AUC) for SI ≥0.70 is 0.62(0.56–0.69) and 0.71(0.66–0.77) for SI ≥ 0.80Back to article page
