[Validated Nomogram Predicting Clinical Outcome after Radiofrequency Ablation in the Treatment of Papillary Thyroid Microcarcinoma].

=0.049)were the strongest predictors for establishing the model.The tumor maximum diameter and RFA energy were the secondary relevant factors for establishing the model.The constructed model showed good performance in both training cohort(AUC=0.762)and validation cohort(AUC=0.740). Conclusion A quantitative model was established for predicting the tumor status within one year after treatment of PTMC by RFA,which can accurately predict the short-term efficacy of RFA and provide a clinical basis for explaining the recovery results of patients.
