Data underlying the publication: Radiofrequency ablation for thyroid nodules (RATED study) - analysis of a learning curve and predictors of success

Context Radiofrequency ablation (RFA) is used as treatment for symptomatic thyroid nodules. However, factors influencing the volume reduction ratio (VRR) at 12 months are not yet fully understood. Objective The primary objective was evaluating the VRR at 12 months after RFA. Secondary objectives were the assessment of a learning curve and factors influencing the VRR at 12 months. Design This is a retrospective Dutch multi-center study. Patients and intervention Patients who underwent RFA for symptomatic thyroid nodules with available ultrasound follow-up were eligible for this study. Main outcome measures Ultrasound based VRR at 12 months and chronologically numbered RFA procedures. All patients’ baseline, ultrasound, treatment, and early follow-up factors were assessed for correlation with VRR at 12 months.
