  • a Plasma enterolactone values were transformed ln(x + 1). Back-transformed values and SDs are presented in nmol/liter. Each characteristic is controlled for others in the table.

  • b Calculated as weight (kg)/height (m2). For women: low normal, <23.1; high normal, 23.1–27.3; and overweight, 27.3–32.2. For men: low normal, <24.3; high normal, 24.3–27.8; and overweight, 27.8–31.1 (34) .
