Following surgery, those at risk for hypocalcemia are prescribed calcium standing dose and patients are also counseled to take additional calcium supplements. It is not possible to calculate an exact dose. Patients often take calcium supplements. Therefore, the additional calcium and the exact duration of when they stopped additional calcium is challenging for patients and was not collected in the trial.","reportingStatus":"POSTED","timeFrame":"Up to 6 months after total thyroidectomy","title":"Duration and Total Daily Dosage of Calcium and/or Vitamin D Supplementation After Surgery","type":"SECONDARY"}
