Effect of Preoperative Vitamin D Deficiency on Hypocalcemia in Patients with Acute Hypoparathyroidism after Thyroidectomy

Table 4

Clinical and biochemical parameters at follow-up visits after hospital discharge.

Parameters	VDD (n = 21)	Non-VDD (n = 22)	value
First follow-up visit
PTH (pg/mL)	19.59 ± 17.22	16.30 ± 7.88	0.42
Albumin-adjusted calcium (mg/dL)	9.07 ± 1.05	8.92 ± 0.77	0.59
Independence from alfacalcidol supplement
Independence from alfacalcidol supplement, n (%)	15 (71.43%)	15 (68.18%)	0.82
Time to independence from alfacalcidol (days) (median, IQR)	50 (36, 61)	16 (8, 30)	0.001

Data are presented as mean ± SD, number and percentage, or median and IQR. A value < 0.05 indicates statistical significance. VDD: vitamin D deficiency; PTH: parathyroid hormone; SD: standard deviation; IQR: interquartile range. Data were collected at 1 year after total thyroidectomy.
