Fig. 5From: Ultrasonographic measurement of the optic nerve sheath diameter to detect intracranial hypertension: an observational studyROC curve. The area under the ROC curve (AUC) was 0.973. From the analysis of the cut-off points, it is observed that a value of 5.7 mm of ONSD maximizes the sensitivity (92.9%) of the method (a greater number of individuals with ICP > 20 mmHg are correctly identified) with a specificity of 88.1%Back to article page
