Receiver operating characteristic (ROC) curve analysis of the relationship between prepontine cistern expansion magnitude and hammer sign probability in patients with iNPH and healthy controls. (a) ROC curves of prepontine cistern area in patients (red) and healthy controls (blue). (b) Box-plot showing significantly greater prepontine cistern area in patients with the hammer sign.
