Relatively Lower FT3 Levels Are Associated with Impaired Quality of Life in Levothyroxine-Treated Patients with Hashimoto Thyroiditis

Table 3

Logistic regression analysis for the association of FT3, FT4, TSH, and QoL in all patients with HT.

	Model 1		Model 2		Model 3
	OR (95% CI)	P	OR (95% CI)	P	OR (95% CI)	P
FT3	0.193 (0.052–0.712)	0.014	0.157 (0.040–0.613)	0.008	0.128 (0.029–0.577)	0.007
FT4	1.217 (0.181–8.196)	0.840	0.993 (0.141–7.014)	0.994	1.781 (0.217–14.603)	0.591
TSH	1.058 (0.803–1.393)	0.689	1.079 (0.815–1.428)	0.595	1.407 (0.971–2.083)	0.071

Model 1: unadjusted; Model 2: adjusted for age, sex, and BMI; Model 3: Model 2 + TPOAb and TGAb, and FT3, FT4, and TSH adjusted for each other.
