Figure 9. Receiver operating characteristic (ROC) curve analysis. ROC curve analysis of MNS1 (A), FRZB (B), OGN (C), LUM (D), SERPINA3 (E), RNASE2 (F), FCN3 (G) and SLCO4A1 (H) in the clinical samples. MNS1, meiosis-specific nuclear structural 1; FRZB, frizzled-related protein; OGN, osteoglycin; LUM: lumican; SERPINA3: serpin family A member 3; FCN3: ficolin-3; SLCO4A1, solute carrier organic anion transporter family member 4A1; RNASE2, ribonuclease A family member 2.
