Table 7.

Features and ROC curve analyses of peripheral biomarkers reported in Figure 2 and published in [56]. Combined Z score has a P value < 0.0001, whereas each parameter has a P value < 0.01 or <0.05. Both sensitivity and specificity were strongly increased by the combination of ROC curves. AUC: Area Under the Curve; FA: fatty acids; TBARS: thiobarbituric acid reactive substances; and MDA: malondialdehyde.
