Table 6 Diagnostic performance of NLR, PLR, SII, and SIRI in differentiating Warthin tumors from pleomorphic adenomas.
| AUC | Sensitivity | Specificity | PPV | NPV | Accuracy | Cut-Off | |
|---|---|---|---|---|---|---|---|
| NLR | 0.59 | 0.66 | 0.54 | 0.48 | 0.71 | 0.58 | 2 |
| PLR | 0.61 | 0.45 | 0.81 | 0.61 | 0.70 | 0.67 | 93.4 |
| SII | 0.53 | 0.31 | 0.80 | 0.50 | 0.64 | 0.61 | 690 |
| SIRI | 0.71 | 0.82 | 0.61 | 0.57 | 0.84 | 0.69 | 0.85 |
| AUC – area under the curve; PPV – positive predictive value; NPV – negative predictive value; NLR – neutrophil to lymphocyte ratio; PLR – platelet-to-lymphocyte ratio; SII – systemic immune inflammation index; SIRI – systemic inflammation response index. | |||||||
