Performance evaluation using receiver operating characteristic curve (ROC, the blue line) of 7 variable-integrated model for predicting unfavorable or favorable outcome in the successfully recanalized AIS patients. The area under the curve was 0.782. The seven variables used in the model were as follows: gender admission NIHSS, HIR, volume of Tmax > 8s, of Tmax > 10s, of Tmax > 12s and volume of rCBF < 30%
