Figure 1
ROC curve analysis illustrating the usefulness of ScvO2 measurement before blood transfusion in order to predict a minimal 5% increase in ScvO2 after BT. The threshold value for ScvO2 with the best sensitivity and best specificity was 69.5% (*sensitivity: 82%, specificity: 76%; area under the curve: 0.831 ± 0.059). Adapted from [7] with permission.

Individual evolutions in ScvO2 before and after blood transfusion (BT) according to agreement (Reco+) or not (Reco-) with the SRLF recommendations for transfusion and according to the ScvO2 before transfusion (< or ≥ 70%). Adapted from [7] with permission.
