Table 3 ROC analysis using CA125, HE4, IL-6, IL-8, RMI score, ROMA alone and predicted probability in combination for distinguishing patients with malignant HGSOC from those with benign ovarian mass, malignant HGSOC from patients with normal ovaries, and benign ovarian mass from patients with normal ovaries in the training phase.
From: Pre-operative sera interleukin-6 in the diagnosis of high-grade serous ovarian cancer
