Figure 2

Receiver operating characteristic curves for Alberta Stroke Program Early Computed Tomography Score (ASPECTS) (A) and CT perfusion (B). State variable: MRI diffusion lesion smaller or larger than 70 mL. Sensitivity, specificity, and Youden index for different ASPECTS cutoff values (C) and CT perfusion core volume cutoffs (D). AUC = area under the curve.
