Within-race risk for BMD Z-score <−2 based on 25(OH)D levels in women with POI (n = 442)

Race/ethnicity	PPR	95% CI	P
Caucasian	1.94	0.88, 4.28	0.099
African-American	6.74	3.17, 14.3	<0.0001
Asian	9.07	4.1, 20.04	<0.0001
Hispanic	3.88	1.35, 11.2	0.012

Data represent serum 25(OH)D deficiency (<32 ng/ml) and risk for Z-score <−2 by race/ethnicity. For 25(OH)D, nmol/liter = 2.496 × ng/ml.
