Bioavailable 25(OH)D Predicts BMD

Model	B	p Value	Adjusted R2
Bioavailable 25(OH)D	0.092	0.002	0.177
Bioavailable 25(OH)D, age, sex, race, and BMI	0.072	0.029	0.180

Note: Bioavailable 25(OH)D and BMD were natural-log-transformed prior to analysis. The coefficient (B) represents the average unit increase in ln BMD for each unit increase in ln bioavailable 25(OH)D. p Value is the statistical significance of the relationship between bioavailable 25(OH)D and BMD after controlling for potential confounders. Thus the relationship between bioavailable 25(OH)D and BMD remains significant after adjusting for potential confounders.
