The ICG group had a lower rate of inadvertent parathyroidectomy (9% vs. 17.9% in the standard group, chi-square test, p = 0.015), a lower rate of postoperative hypoparathyroidism (18.6% vs. 35.3%, chi-square test, p = 0.001), and higher postoperative PTH levels (t-test, p = 0.0001). The gene discussed is PTH; the disease is hypoparathyroidism.
