Comparison of predictive power among the NIHSS and each sub-item score on functional independence after endovascular recanalization. The AUC is provided, suggesting that consciousness score (0.716) in NIHSS was better able to predict functional outcome than all others. 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.
