Association between ATA risk groups and the state of disease of disease at the final follow-up.

ATA risk group/state of disease at final follow-up	SED (n  = 6)	BED (n  = 3)	Indeterminate (n  = 5)	NED (n  = 17)
ATA intermediate risk (n  = 21)	3 (14.3%)	1 (4.8%)	4 (19.0%)	13 (61.9%)
ATA high risk (n  = 12)	3 (25.0%)	3 (25.0%)	1 (8.3%)	5 (41.7%)

ATA, American Thyroid Association; BED, biochemical evidence of disease; NED, no biochemical or structural evidence of disease; SED, structural or functional evidence of loco-regional or distant metastases.
