Mean preoperative TSH.

	Number of patients	Mean TSH (mIU/L)	value
All euthyroid patients
DTC	164	2.10 ± 0.07	0.004
TCLS	111	2.18 ± 0.09	0.001
DTMCs	53	1.94 ± 0.12
BTND	630	1.86 ± 0.04
Excluding patients with positive autoantibodies
DTC	126	2.14 ± 0.08	<0.001
TCLS	85	2.23 ± 0.10	<0.001
DTMCs	41	1.96 ± 0.14
BTND	519	1.81 ± 0.04
Excluding patients with HT
DTC	151	2.11 ± 0.07	0.001
TCLS	104	2.19 ± 0.09	<0.001

DTMCs: differentiated thyroid microcarcinomas; TCLS: thyroid cancers of larger size; HT: Hashimoto thyroiditis; BTND: benign thyroid nodular disease; and TSH: thyroid-stimulating hormone. Euthyroid based on TSH alone; described as mean ± SE; comparing group with DTC to group with BTND; comparing among groups with TCLS, DTMCs, and benign diseases.
