Receiver operating characteristic (ROC) curves for the ordinal and dichotomized Auto-, NCCT- and CTP-ASPECTS in patients with AIS. The areas under the curve (AUCs) of the ordinal Auto-, NCCT- and CTP-ASPECTS for predicting patients with good clinical outcome were 0.697, 0.730 and 0.870 (a), respectively. The AUCs of the dichotomized ASPECTS with a cutoff of > 5 was 0.676, 0.667 and 0.829 for the three scoring methods (b), respectively. Significant differences were observed between the areas of the ordinal or dichotomized CTP- and NCCT-ASPECTS and CTP- and Auto-ASPECTS, but no significant differences were observed between the areas of the ordinal or dichotomized Auto- and NCCT-ASPECTS
