The ROC curve analysis of different indexes for differentiating hemorrhagic MMD or MMS from non-hemorrhagic MMD or MMS. (A) ROC curve analysis of age, gender, Suzuki stage (Suzuki 3–4), dilation of AChA (Grade 2) and PComA (Grade 2), and aneurysm for predicting hemorrhagic MMD or MMS (P < 0.0001, AUC = 0.8748). (B) ROC curve analysis of F-V ratio (the ratio of CFCT to CVCT) for predicting hemorrhagic MMD or MMS (P < 0.0001, AUC = 0.8016, best cut-off point 0.4344; sensitivity 81.4%, specificity 73.2%). (C) ROC curve analysis of the F-V ratio, combined with age, gender, Suzuki stage (Suzuki 3–4), dilation of AChA and PComA and aneurysm, for predicting hemorrhagic MMD or MMS (P < 0.0001, AUC = 0.9206).
