Association between sensitivity to thyroid hormones and non-high-density lipoprotein cholesterol levels in patients with type 2 diabetes mellitus

Figure 2 Comparison of thyroid-associated variables in different non-high-density lipoprotein cholesterol level groups. Data were analyzed by Student t-test or Mann-Whitney U test. A: Free triiodothyronine (FT3); B: Free thyrotropin (FT4); C: Thyroid-stimulating hormone (TSH); D: FT3/FT4; E: TSH index; F: Thyrotrophic T4 resistance index; G: Thyroid feedback quantile-based index. Non-HDL-C: Non-high-density lipoprotein cholesterol; FT3: Free triiodothyronine; FT4: Free thyrotropin; TSH: Thyroid-stimulating hormone; TSHI: Thyroid-stimulating hormone index; TT4RI: Thyrotrophic T4 resistance index; TFQI: Thyroid feedback quantile-based index.
