Figure 3

Association between angiographic findings and the DIVAA ratio. Assessment of the receiver operator characteristic (ROC) curve for the predictive power of the directed in vivo angiogenesis assay (DIVAA) ratio in patients having received autologous CD34+ cell treatment. The area under the ROC curve (AUC) was 0.8519 (). The optimal cut-off point is labeled by the red solid circle.
