No Association between Neck Circumference and Free Triiodothyronine in Euthyroid Men

Table 2

Linear regression analysis for the associations of FT3 with NC, WC, and BMI.

Variables	NC		WC		BMI
	Standardized β (t)	value	Standardized β (t)	value	Standardized β (t)	value
Unadjusted model	0.073 (1.989)	0.047	0.164 (4.500)	<0.001	0.169 (4.635)	<0.001
Multivariate model	–0.015 (–0.378)	0.705	0.103 (2.520)	0.012	0.082 (1.990)	0.047

Multivariate model: adjustment was for age, SBP, DBP, HbA1c, HOMA-IR, TC, TG, HDL-c, LDL-c, and CRP. FT3: free triiodothyronine; NC: neck circumference; WC: waist circumference; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; HbA1c: glycated hemoglobin A1c; HOMA-IR: homeostasis model assessment-insulin resistance index; TC: total cholesterol; TG: triglyceride; HDL-c: high-density lipoprotein cholesterol; LDL-c: low-density lipoprotein cholesterol; CRP: C-reactive protein.
