Table 4 Values from the ROC curve of the FR indices

From: Fluid responsiveness in liver surgery: comparisons of different indices and approaches

	Threshold value	Sensitivity	Specificity	AUC
PPV	13.9	0.88	0.86	0.82
PPV_PiCCO	14.4	0.88	0.86	0.92
SVV_PiCCO	19.7	0.88	0.75	0.88
SVV_SA	18.2	0.82	0.71	0.80
SVV_LM	9.4	0.76	0.71	0.74
SPV	8.1	0.88	0.86	0.87

Threshold, sensitivity, specificity, and AUC values are estimated from the ROC curve. These values refer to the maneuvers classified according to the maximum value of CO variation registered in the second time window.
