Single marker performance.

a)Sens98 = Sensitivity at 98% specificity in discriminating cases from all controls (Healthy Controls, Surgical Benigns and Surgical Normals). b)Sens95 = Sensitivity at 95% specificity in discriminating cases from all controls (Healthy Controls, Surgical Benigns and Surgical Normals). c)AUC = Area Under (ROC) Curve for discriminating cases from all controls (Healthy Controls, Surgical Benigns and Surgical Normals). d)Discriminatory Dist. = Discriminatory Distance. The logarithm of serum marker concentrations were normalized to standard deviations from the mean of the corresponding measurements in Healthy Controls. Mean, SE (95% CI) = Mean, standard error, and 95% confidence intervals of difference between normalized serum marker concentration in cases and in Healthy Controls.
