Fig. 5From: 3D slicer-based calculation of hematoma irregularity index for predicting hematoma expansion in intracerebral hemorrhageReceiver operating characteristic curve analysis. ROC curve analysis using a binary definition of hematoma expansion revealed that an area under the curve was 0.86 (P < 0.01), and the best cutoff of HII for predicting hematoma growth was 123.8% (sensitivity 81%, specificity 83%).
