Figure 3

ROC curve analysis of the indexes. Red indicates the lactic acid group, for which the area under the curve is 0.9272, the corresponding standard error is 0.01534, , and the 95% confidence interval is (0.8971, 0.9573). Green indicates the inferior vena cava variability group, for which the area under the curve is 0.8652, the corresponding standard error is 0.02042, , and the 95% confidence interval is (0.8251, 0.9052). Blue indicates the CVP suite, for which the area under the line is 0.633, the corresponding standard error is 0.032, , and the 95% confidence interval is (0.5702, 0.6957).
