Performance of OSCC biomarker candidates in the validation set
| Validation set | |||
|---|---|---|---|
|
| |||
| AUC | Sensitivity | Specificity | |
| Nonanoic acid | 0.909 | 0.840 | 0.929 |
| Glucose | 0.889 | 0.640 | 1.000 |
| Galactose | 0.946 | 0.920 | 0.929 |
| Cysteine+Cystine | 0.774 | 0.840 | 0.714 |
Biomarker candidates revealed a high value of ≥0.85 except cysteine in the AUC, but it was somewhat low as 0.77 for cysteine, but it still showed moderate accuracy as a biomarker candidate. In sensitivity, biomarker candidates showed over 0.85 except glucose, which was slightly lower, 0.64.
