Serum pro-inflammatory cytokines as potential biomarkers for the diagnosis of gastric carcinoma

Figure 2 receiver operating characteristic curves of differential pro-inflammatory cytokines in identification of patients with gastric carcinoma from healthy volunteers. A: Receiver operating characteristic (ROC) curve of interleukin (IL)-1β; B: ROC curve of IL-6; C: ROC curve of IL-8; D: ROC curve of interferon-γ (IFN-γ); E: ROC curve of a combined panel of IL-1β, IL-6, IL-8, and IFN-γ. IL: Interleukin; AUC: Area under the curve; IFN-γ: Interferon-γ.
