Associations between the weighted quantile sum regression indexes composed for multiple vitamins and BMDs by WQS among participants in NHANES 2005–2006

	Outcome	βWQS	95%CI	P
Positive	Total femur BMD	0.010	(0.001, 0.018)	0.021
	Femoral neck BMD	0.008	(0.001, 0.015)	0.022
Negative	Total femur BMD	-0.003	(-0.011, 0.005)	0.457
	Femoral neck BMD	-0.007	(-0.015, 0.001)	0.099

Models were adjusted for age, sex, race, family poverty-to-income ratio, education, body mass index, calcium concentration, physical activity, drinking status, smoking status, regular milk consumption, osteoporosis family history, prednisone/cortisone intake daily, diabetes, and hypertension
