Table 2. Diagnostic and predictive values of pre-ablation Tg* and TSH* for a successful therapeutic outcome.
| Cutoff values | Accuracy | Sensitivity | Specificity | PPV* | NPV* | AUC* (95% CI*) | P values | |
|---|---|---|---|---|---|---|---|---|
| Pre-ablation Tg* | 3.525 ng/mL | 75.24% | 77.12% | 74.12% | 64.09% | 84.39% | 0.843 (0.801–0.885) | <0.001 |
| Pre-ablation TSH* | 99.700 μIU/ml | 57.46% | 57.63% | 57.46% | 44.74% | 69.33% | 0.605 (0.542–0.667) | 0.002 |
*Tg = thyroglobulin, TSH = thyroid stimulating hormone, PPV = positive predictive value, NPV = negative predictive value, AUC = area under the curve, CI = confidence interval.
