Hidden IgG Antibodies to the Tumor-Associated Thomsen-Friedenreich Antigen in Gastric Cancer Patients: Lectin Reactivity, Avidity, and Clinical Relevance

Figure 7

A receiver operator characteristic (ROC) curve analysis for the HAb level in stage 3 patients (a); in stage 3 females (b); and for the ratio anti-TF IgG avidity in tIgG/anti-TF IgG avidity in the serum of stage 3 males (c) and stage 3 females (d). The area under the ROC curve represents the diagnostic accuracy of the changes for gastric cancer.
