  1. Summary of 2 linear regression models selected by forward stepwise variable selection per Materials and Methods. Each overall model was highly predictive of the MA measured during shock (OD = 80 ml/kg) or the change (Delta) in MA from baseline to shock. Fibrinogen and ScvO2 played important roles within each selected model.
