group and 342 patients in the post-ATA2009
group. Fewer non-diagnostic fine-needle aspiration cytology results were identified in the post-ATA2009
group (4% versus 0.9%; P = 0.01), while the rates of other fine-needle aspiration cytology categories were similar. There was a reduction in the use of radioactive iodine ablation in the post-ATA2009
group, both in the proportion of patients being treated (66% versus 48%; P < 0.001) and the dosages used (mean 96 mCi versus 80 mCi; P < 0.01), despite similar tumour size in both groups.
