Fig. 4From: Determination of sialic acid in saliva by means of surface-enhanced Raman spectroscopy as a marker in adnexal mass patients: ovarian cancer vs benign casesSensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for each test. The Figure includes cutoff values and confidence intervals for each biomarker, as well as for the calculated MRI. Abbreviations: SA, sialic acid; MRI, Malignancy risk, index, CA125 > 35, CA-125 larger than 35 U/mL; CA125 > 216.5, CA-125 larger than 216.5 U/mLBack to article page
