In contrast, in our study, a higher incidence of postoperative temporary hypocalcemia was observed in the group of patients with postoperative PTH levels < 12 pg/mL, and there was a significant difference in PTH levels between patients with postoperative hypocalcemia (16.7 ± 5.13 pg/mL) and patients with normocalcemia (32.2 ± 24.4 pg/mL, p < 0.001), and overall, patients with postoperative hypocalcemia had 65.7% lower PTH levels compared to preoperative levels, and this difference was even more pronounced in patients with postoperative PTH levels < 12 pg/mL (90.1%). The gene discussed is PTH; the disease is Hypocalcemia.
