About

The goal of this retrospective observational study is to determine whether vitamin D levels differ in patients with Hashimoto's thyroiditis (HT) compared to those without Hashimoto's thyroiditis. The main research questions are:

Are vitamin D levels lower in HT patients compared to non-HT patients? Do vitamin D levels vary between HT and non-HT patients based on thyroid function status?

The study was conducted by retrospectively reviewing the medical records of patients who visited the hospital outpatient clinic.
