Figure 2A shows the ROC curves for TK 210 ELISA (TK1p) alone, CA 125 alone, HE4 alone, and the dual markers (TK 210 + CA 125, TK 210 + HE4, and TK 210 + ROMA index) when these combinations were calculated for the 198 samples (134 ovarian tumors and 64 healthy controls). The gene discussed is WFDC2; the disease is ovarian neoplasm.
