ROC curve of minimum StO2, cardiac index, SvO2 and mean arterial pressure versus lactate clearance. Minimum values of StO2 (Min-StO2), cardiac index (Min-CI), SvO2 (Min- SvO2) and mean arterial pressure (Min-MAP) from T 0 to T d1 were compared with a lactate clearance of <10 % and ≥10 % at T d1. The area under the curve is 0.83 for StO2 (95 % CI 0.65–1.02; p <0.01), 0.64 for cardiac index (95 % CI 0.37–0.91; p = 0.22), 0.56 for SvO2 (95 % CI 0.36–0.75; p = 0.61) and 0.47 for mean arterial pressure (95 % CI 0.27–0.67; p = 0.80)
