Accuracy of cIVC at baseline, IVCmax and ∆CO after PLR for predicting fluid responsiveness

	Se	Sp	LR+	LR-	PPV	NPV
cIVC > 42 %	31 %	97 %	9	0.7	90 %	59 %
IVCmax at baseline < 2.1 cm	93 %	33 %	1.4	0.2	57 %	83 %
ΔCO > 10 %	52 %	87 %	4	0.6	79 %	65 %

∆CO change in CO between baseline and after PLR, cIVC collapsibility index at baseline, IVCmax maximum diameter of the IVC, PLR passive leg raising, Se sensitivity, Sp specificity, LR likelihood ratio, PPV positive predictive value, NPV negative predictive value
