Abstract

If these complaints continued for at least 30 minutes, the presence of prolonged prominent complaints was accepted. Patients who developed prolonged complaints were categorized as group 1 and patients without prolonged complaints as group 2.
Results: The number of patients diagnosed with euthyroid goiter was significantly higher in Group 1 (p
