Figure 5.

Receiver operating characteristics (ROC) curves of examined growth factors as clinical indicators of gastric carcinoma. Calculated sensitivity (y-axis) is plotted against 1-specificity formula (x-axis) for examined growth factors, that is (A) HGF, (B) VEGF, (C) FGF, (D) IGF-1 and (E) G-CSF. AUC - area under curve; p - level of significance; HGF - hepatocyte growth factor; VEGF - vascular-endothelial growth factor; IGF-1 - insulin-like growth factor-1; FGF - fibroblast growth factor; G-CSF - granulocyte-colony stimulating factor.
