Performance of the level of serum thyroglobulin and neutrophil elastase in detecting recurrence of differentiated thyroid cancer evaluated using receiver operating characteristic curve (ROC) analysis. Values for area under the ROC curve (AUC) for each curve are presented with the 95% CI. The biomarker ‘Thyroglobulin + neutrophil elastase’ represents a combined model of thyroglobulin and neutrophil elastase.
