A total of 66 randomized participants did not complete the study (23 in the soy isoflavone group and 43 in the placebo group).1 A comparable number of women in each group reported moving out of state, having a sick family member, a new job, or a desire to eat soy products as the reason to discontinue their participation. Although there was a marked difference in the proportion of participants who were no longer interested in participating in the study or were lost to follow-up (16 [19%] in the soy isoflavone group and 30 [34%] in the placebo group), we did not find any objective measures that could explain this difference.
