Table 2.

Stepwise multiple regression analysis between age, BMI, IGFBP-3, and IL-6 considering LS/FN BMD as dependent variables.

Variables	LS BMD			FN BMD
	β	P	R 2	β	P	R 2
Age	-0.178	0.015	0.38	-0.126	0.011	0.32
IGFBP-3	-0.304	<0.001		-0.328	0.003
IL-6	-0.285	0.004		-0.301	0.012

BMI: body mass index; IL-6: interleukin 6; LS: lumbar spine; FN: femoral neck.
