Effect of soy isoflavones and placebo on insulin secretion. Values are means ± S.D. A, B) There were no differences within groups in first or second phase insulin secretion with soy isoflavones or with placebo (differences within groups based on paired t-test). C) There were no differences between groups in the area under the curve (AUC) in pmol/min for first or second phase insulin secretion (differences between groups based on unpaired t-test).
