The main questions it aims to answer are:\n\n* How common is post-thyroidectomy hypoparathyroidism in Estonia?\n* What are the most significant risk factors for the development of post-thyroidectomy hypoparathyroidism in Estonia?\n* Are magnesium levels a risk factor for the development of hypoparathyroidism? Participants will be asked to answer a questionnaire about risk factors. The study collects data on risk factors for hypoparathyroidism following thyroid surgery, including patient questionnaires and comorbidities, pre- and postoperative laboratory tests and surgery-related risk factors.",[64],"Post-Surgical Hypoparathyroidism",[66,67,68],"thyroidectomy","hypoparathyroidism","risk factors","2026-05-05",{"date":71,"type":72},"2026-05-13","ACTUAL",{"date":74,"type":72},"2025-10-13",{"date":76,"type":60},"2028-12",{"name":5,"class":6},2]
