Analysis of risk factors and development of a risk prediction model for postoperative hypocalcemia in differentiated thyroid cancer

Diabetes history, bilateral thyroidectomy, lateral lymph node dissection, capsular invasion, prolonged surgical time (≥82.5 min), and increased intraoperative bleeding (≥25.5 mL) are significant risk factors for postoperative hypocalcemia in DTC patients. The Nomogram model, integrating these factors, outperforms iPTH-based predictions and offers a precise tool for preoperative risk assessment and postoperative management to reduce hypocalcemia and improve patient outcomes.
