Univariate and multivariate logistic regression identified that PTH level reduction was an independent risk factor for transient hypocalcemia in the whole cohort (β = 0.043, OR = 1.044, 95% CI 1.023–1.065, p < 0.001), bilateral group (β = 0.042, OR = 1.043, 95% CI 1.022–1.064, p < 0.001), and female patients (β = 0.049, OR = 1.050, 95% CI 1.026–1.075, p < 0.001). Here, PTH is linked to Hypocalcemia.
