Figure 2 Receiver-operating characteristic curves for the prediction of a two-year outcome according to baroreflex sensitivity by the transfer function method (TF-BRS) (solid line) and left ventricular ejection fraction (LVEF) (dotted line). The identity line indicates no predictive discrimination. The area under the curve was 0.68 ± 0.06 for TF-BRS and 0.61 ± 0.05 for LVEF.
