Cut-off levels, sensitivities and specificities of biomarkers for development of RA in patients with UA.
| Biomarker | Optimal Cut-Off | Sensitivity (%) | Specificity (%) |
|---|---|---|---|
| IL-15 | 36.4 pg/mL | 77.8 | 80.9 |
| anti-CCP Abs | 62.8 IU/mL | 66.7 | 76.6 |
| RF | 20.9 IU/mL | 61.1 | 87.2 |
Areas under the ROC curves were used to compute sensitivity and specificity of biomarkers and to determine the optimal cut-offs.
