Distribution of log10 equol/daidzein ratio.
The urinary isoflavone data were expressed using the log10 equol/daidzein ratio. The distribution of this ratio showed a mixture of two normal distributions, considering the left-hand distribution to represent non-producers and the right-hand distribution to represent equol producers.
