Fig. 4From: Assessment of a panel of tumor markers for the differential diagnosis of benign and malignant effusions by well-based reverse phase protein arrayReceiver operating characteristic (ROC) curves. The ROC curves were plotted depending on MUC1 (a), EMA (b), and other tumor markers (HSP90, Pan-CK, TGF-β, and CA125) (c). Operating characteristics of six tumor markers for malignant effusion diagnosis (d). Relative expressional signals were represented as a ratio after normalization with GAPDHBack to article page
