The change of concentrations of Bone metabolic markers in serum

Group		Ca (mmol/L)	P (mmol/L)	ALP (IU/L)
Group I (n = 37)	Before taking isoflavone	2.33 ± 0.10	0.95 ± 0.14	59.37 ± 18.66
	After taking isoflavone	2.53 ± 0.16*	0.94 ± 0.14	53.9 ± 13.76*
Group II (n = 33)	Before taking isoflavone	2.30 ± 0.09	0.97 ± 0.12	57.37 ± 18.18
	After taking isoflavone	2.39 ± 0.10*	0.98 ± 0.11	56.53 ± 18.85

Concentrations of bone metabolic markers in serum of subjects in isoflavone group and placebo group after 6 months of treatment with soy isoflavone 90 mg/day. Experimental conditions and treatment procedures are given in Materials and Methods. Graph depicts (mean ± SD). Asterisk means significant against baseline before trial (*p<0.05), t test.
