Fig 1. Comparison of the ability to predict early complications of acid base changes alone (black), addition of coagulopathy (red), addition of acute hemorrhage (green), and addition of soft tissue injuries (blue).

The addition of these parameters lead to a sustained improvement in prediction of complications. Early Complications include Death within 72 hours, Death from traumatic brain injury, Death from exsanguination. AUC = Area Under the Curve. 95%CI = 95% Confidence Interval.
