ROC curve analysis. A. Intraplaque neovascularization level, plaque stiffness and a combination of both predicted 90-day neurological outcome mRS score 2 to 6: IPN grade (blue line, AUC = 0.73), plaque stiffness (red line, AUC = 0.76) and combined application (green line, AUC = 0.85) ROC curves. The highest identification accuracy was achieved with the combined application, AUC = 0.85. B. Intraplaque neovascularization level predicts 90-day neurological outcome mRS score 3 to 6 with AUC 0.79. IPN = intraplaque neovascularization, PS = plaque hardness, AUC = area under the ROC curve, CI = confidence interval
