Serum Antithyroglobulin Antibody Levels Are Associated with Diabetic Retinopathy among Euthyroid Type 2 Diabetes Patients: A Hospital-Based, Retrospective Study

Figure 2

The variation of different stages of DR prevalence with serum TSH (a), FT4 (b), and FT3 (c). DR: diabetic retinopathy; NPDR: nonproliferative diabetic retinopathy; PDR: proliferative diabetic retinopathy; TSH: thyroid-stimulating hormone; FT4: free thyroxine; FT3: free triiodothyronine. The stratification of the thyroid indicators is stated in the figure, and the unit of TSH, FT4, and FT3 should be mU/L, pmol/L, and pmol/L, respectively. The indicates that the corresponding prevalence was significantly higher than the control group (T1) ().
