Table 4. Spearman correlation coefficients for isoflavone intake on 2-day dietary records and mean of urinary isoflavonoid measurements among participants on a regular diet.

Dietary intake (mg/day)		Urinary excretion (µmol/24 hours)		r
Daidzein	7.57 ± 12.12	Total daidzeina	19.79 ± 22.93	0.55e
Genistein	10.18 ± 17.38	Total genisteinb	6.42 ± 9.69	0.60e
Glycitein	1.05 ± 2.72	Total glyciteinc	1.98 ± 2.85	0.50e
Isoflavone	18.80 ± 31.96	Total isoflavoned	28.18 ± 31.85	0.58e

^aTotal daidzein = daidzein plus its metabolites dihydrodaidzein, equol, and O-desmethylangolensin.

^bTotal genistein = genistein plus its metabolite dihydrogenistein.

^cTotal glycitein = glycitein plus its metabolite dihydroglycitein.

^dTotal isoflavone = total daidzein + total genistein + total glycitein.

^eP < 0.01.
