Clinical Usefulness of Bioavailable Vitamin D and Impact of GC Genotyping on the Determination of Bioavailable Vitamin D in a Korean Population

Table 3

Comparison of genotype-independent and genotype-specific bioavailable 25(OH)D concentrations according to medical status.

	Genotype-independent bioavailable 25(OH)D (ng/ml)	Genotype-specific bioavailable 25(OH)D (ng/ml)	Mean percent difference between genotype-independent and genotype-specific bioavailable 25(OH)D	value
Total subjects ()	2.4 (1.4-3.6)	2.5 (1.3-3.8)	2.3%	0.299
Healthy controls ()	3.0 (2.6-4.3)	2.9 (2.5-4.2)	-0.9%	0.073
Patients with LC ()	2.4 (1.4-3.9)	3.0 (1.5-4.8)	8.4%	0.077
Pregnant women ()	1.2 (0.8-1.7)	1.2 (0.8-1.8)	-0.5%	0.058

Values are presented with median (interquartile range). LC: liver cirrhosis; 25(OH)D: 25-hydroxy vitamin D.
