Comparison of predictive power among NIHSS, ASPECTS and the combination on the functional independence after endovascular recanalization. The AUC suggests that the combination (0.793) was better able to predict functional outcome than NIHSS and ASPECTS each alone. ROC, receiver operating characteristic; AUC, area under ROC curve, a frequently used tool for assessing the overall accuracy of a diagnostic marker (scoring range 0.5-1, higher core indicating better efficacy); NIHSS, the National Institute of Health Scale Score; ASPECTS, Alberta Stroke Program Early Computed Tomography Score.
