Background: Type 2 diabetes mellitus (T2DM) and thyroid disorders are common endocrine disorders. This case-control study aims to determine the prevalence and predictors of thyroid disorders in T2DM patients.
Methods: A total of 998 T2DM patients attending a tertiary hospital were included and underwent investigations for thyroid function: thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3); and glycated hemoglobin (HbA1c).
