Summary

This study looked at 300 patients who had their thyroid gland removed. Doctors wanted to see if measuring parathyroid hormone (PTH) right after surgery could reliably rule out hypoparathyroidism, a condition where calcium levels drop too low. The goal was to find a PTH cutoff value that gives doctors confidence that the patient will not develop this complication.
