Fig. 8From: Developing a model for estimating infarction onset time based on computed tomography radiomics in patients with acute middle cerebral artery occlusionThe receiver operating characteristic curve of the radiomics signature (AUC, 0.755 [0.614–0.897]) and combined model (AUC, 0.820 [0.712–0.928]) for discriminating the TFS in the external validation cohort (A). The radiomics signature had a a better performance with a threshold probability range of 0.20–0.86 in the external validation cohort (B). The combined model had a better performance with a threshold probability range of 0.06–0.57 in the external validation cohort (C)Back to article page
