Vitamin D and Parathyroid Hormone Status in Female Garment Workers: A Case-Control Study in Bangladesh

Table 3

Serum concentration of vitamin D [25(OH)D], PTH, calcium, and ALP in the study subjects.

Variables	Case ()		Control ()		value
	Mean ± SD	Median (range)	Mean ± SD	Median (range)
25(OH)D (ng/mL)	14.2 ± 2.6	14.3 (7.0–18.5)	22.4 ± 2.4	22.1 (18.6–30.1)	<0.001
PTH (pg/mL)	33.9 ± 17.2	32.6 (7.9–90.0)	35.9 ± 16.3	34.5 (12.0–80.0)	0.609
Calcium (mg/dL)	9.1 ± 0.6	9.2 (7.5–10.0)	9.3 ± 0.6	9.3 (7.5–10.5)	0.057
ALP (U/L)	117.2 ± 14.4	123.0 (80.0–135.0)	80.5 ± 30.6	79.0 (36.0–125.0)	<0.001

values obtained by comparing the mean concentration of variables of case and control group. Independent sample -test was used to evaluate the results.
