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

Table 2

Comparison of parathyroid glands preservation between VDD and non-VDD groups.

Preservation status	VDD (n = 21)	Non-VDD (n = 22)	value
Parathyroid glands identified and preserved during surgery, n (%)
1 parathyroid gland	2 (9.5%)	0	0.686
2 parathyroid glands	6 (28.6%)	8 (36.4%)
3 parathyroid glands	3 (14.3%)	3 (13.6%)
4 parathyroid glands	10 (47.6%)	11 (50.0%)
Parathyroid glands identified on histological examination, n (%)
0 parathyroid glands	13 (61.9%)	16 (72.7%)	0.415
1 parathyroid gland	8 (38.1%)	5 (22.7%)
2 parathyroid glands	0	1 (4.5%)

A value < 0.05 indicates statistical significance. VDD: vitamin D deficiency.
