Figure 2From: Diagnostic accuracy of cerebrospinal fluid protein markers for sporadic Creutzfeldt-Jakob disease in Canada: a 6-year prospective study Receiver Operating Characteristic (ROC) curves for tau and S100B, plotted for 913 sCJD and non-CJD patients on whom both markers were assayed. Solid line indicates ROC curve for tau; dashed line indicates ROC curve for S100B; dotted line indicates diagonal representing a hypothetical test with no diagnostic discrimination.Back to article page
