Receiver operating characteristic (ROC) curve associated with prediction of functional outcome for rtPA-treated acute ischemic stroke in the telestroke. Higher area under the curve (AUC) values in ROC analysis indicate better discrimination of the score for the measured outcome. Classification table (overall correctly classified percentage = 79.9%) and area under the ROC curve (AUC = 0.829, 0.780-0.877) were applied to check the model fitness.
