Table 8

Linear logistic regression analysis.

Dependent variable	Independent variables	OR (95% CI)	value
Postoperative transient hypocalcemia	25-OHD ≤ 10 (ng/mL) + injection	1.199 (0.511–2.813)	0.676
	10 < 25-OHD ≤ 20 (ng/mL) + no injection	1.603 (1.001–2.567)	0.050
	25-OHD ≤ 10 (ng/mL) + no injection	1.662 (1.178–2.345)	0.004

Data are expressed as odds ratio (OR) and 95% confidence interval (CI). A value <0.05 was considered statistically significant. 25-OHD, 25-hydroxyvitamin D; ETE, extrathyroidal extension.
