Table 1 summarizes the clinical characteristics of T2DM patients with different BCAA levels. The thyroid function parameters (T3 (p < 0.001), T4 (p < 0.01), FT3 (p < 0.001), and FT4 (p < 0.05)), triglyceride (TG) levels (p < 0.001), and the prevalence of current statin use (p < 0.05) were lower in the first tertile of BCAA levels compared to the second and third tertiles. In addition, the prevalence of current insulin use was higher in the first tertile compared to the second and third tertiles of BCAA levels (p < 0.01). Here, INS is linked to type 2 diabetes mellitus.
