From: The prognostic value of optic nerve sheath diameter in patients with subarachnoid hemorrhage
a, b Receiver operating characteristic curves for predicting poor outcomes using Hunt and Hess grade, the optic nerve sheath diameters, and their modifications (a). Although there were no differences between the areas under the curve (AUCs) of H-H grade, follow-up ONSDaverage, and follow-up ONSDindex, the performance of a composite of H-H grade and follow-up ONSDindex was strongly associated with poor neurological outcomes compared with the use of either marker alone (all p < 0.006) (b).
