The ROC curve of plasma cytokine levels for patients with different prognosis. The AUC of the ROC curve for IL-6, IFN-γ, G-CSF, M-CSF, IL-2 Ra, MCP-1, MCP-3, HGF was estimated. A The ROC curve of each cytokine. B The ROC curves of different combination of two cytokines from IL-6, G-CSF, M-CSF, IFN-γ, MCP-1 and IL-2 Ra. All the P values were less than 0.05. ROC, receiver operating characteristic; AUC, area under the curve
