TPO and Hashimoto thyroiditis: In Pearson’s correlation test, positive correlation was found between lymphocytic thyroiditis and preoperative TSH (r=0.161, p=0.010), anti-TPO (r=0.262, p=0.000), and preoperative anti-TG (r=0.171, p=0.016) values, but negative correlation was found with age (r=–0.152, p=0.015).
