ROC curve of StO2 , cardiac index, SvO2 and mean arterial pressure versus lactate clearance. Measured values 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 0.65 for StO2 (95 % CI 0.55–0.75; p <0.01), 0.62 for cardiac index (95 % CI 0.51–0.72; p <0.05), 0.47 for SvO2 (95 % CI 0.37–0.58; p = 0.63) and 0.46 for mean arterial pressure (95 % CI 0.35–0.58; p = 0.51)
