Comparison of the AUC values of salivary MMP‐1 and several clinical markers.
| AUC | 95% CI | p‐value | p‐value | |
|---|---|---|---|---|
| Salivary MMP‐1 | 0.638 | 0.580–0.697 | .041 a | ‐ |
| TNM stage | 0.639 | 0.585–0.693 | <.001 a | .187 |
| NLR | 0.620 | 0.559–0.681 | .018 a | .987 |
| PLR | 0.575 | 0.513–0.637 | .143 | .125 |
| Albumin | 0.530 | 0.464–0.595 | .110 | .021 a |

| CCI | 0.568 | 0.505–0.631 | .002 a | .048 a |
Note: The AUC values between the salivary MMP‐1 and other markers were compared using the Z test.
Abbreviations: AUC, area under the curve; CCI, Charlson Comorbidity Index; CI, confidence interval; NLR, neutrophil‐to‐lymphocyte ratio; PLR, platelet‐to‐lymphocyte ratio; SCCA, squamous cell carcinoma antigen.
