Cox Analysis Hazard Rate (HR) Estimates for Progressing Tumor Size.

Tumor Size	Received Some Form of Thyroid Cancer-directed Treatment (n=28,261)			Did Not Receive Any Thyroid Cancer-directed Treatment (n=467)
Tumor Size	HR (adjusted)	P Value	95% CI	HR (adjusted)	P Value	95% CI
T1a (≤10 mm)	Ref	-	-	Ref	-	-
T1b (>10 to ≤20 mm)	0.926	0.77	(0.55, 1.54)	1.12	0.08	(0.98, 1.28)
T2 (>20 to ≤30 mm)^*	1.393	0.21	(0.82, 2.35)	1.23	0.01	(1.04, 1.44)
T2 (>30 to ≤40 mm)^*	1.784	0.04	(1.01, 3.14)	1.71	0.00	(1.43, 2.06)

^*For purposes of analysis the T2 group was split into two groups based on size.
