Further, we did not evaluate whether thyroid nodules were calcified or not (ostensibly, calcified thyroid nodules might cause more compressive symptoms), nor did we qualify whether the thyroid nodules were in an anterior or posterior location (ostensibly, posterior left sided thyroid nodules might be more likely to cause dysphagia compared to anterior left sided thyroid nodules). Additional studies should be conducted in similar populations with a particular focus on factors predicting greater response to RFA and comparing the performance of RFA with other procedures.".
