New serum biomarkers for detection of HBV-induced liver cirrhosis using SELDI protein chip technology

Figure 1 SELDI-TOF mass spectra. Spectra 1-4 from HBV-induced LC patients, 5-8 from healthy men, and 9-12 from HCC patients. A biomarker of M_r 7772 was present in non-cirrhotic group, but not in LC serum samples.

Figure 2 SELDI-TOF mass spectra. Spectra 1-4 from HBV in-duced LC patients, 5-8 from healthy men, and 9-12 from HCC patients. A biomarker of M_r 3933 was present in non-cirrhotic group, but not in LC serum samples.

Figure 3 Tree structure and sample distribution. The root node and descendant nodes are indicated in gray, and the ter-minal nodes are shown in black. Peaks with M_r 7772 and 3933 were chosen to set up the decision tree.
