A machine learning prediction model and online calculator for postoperative recurrence of secondary hyperparathyroidism: A dual-center development and validation study.
BACKGROUND Secondary hyperparathyroidism carries a high recurrence risk after parathyroidectomy (PTX), requiring early identification of high-risk patients. Using a two-center cohort, we developed a machine learning prediction model and deployed it as an online calculator. METHODS We included 391 SHPT patients underg...
