^aComparison with AUC = 0.5. AUC, area under the ROC curve; CI, confidence interval; CVP, central venous pressure; GEDV, global end-diastolic volume; PPV, pulse pressure variation; r², Pearson correlation coefficient; ROC, receiver operating characteristic; ΔSV, % change in stroke volume; SVV, stroke volume variation.
