Prenatal Nutritional Supplementation

My first reaction to this report (pp 683 to 697) is that something must be wrong and I assume many others will react the same way. If feeding pregnant women has an unfavorable effect upon the outcome of pregnancy we are really in a bad way! We need to examine possible reasons for this unanticipated result. I will comment on several of these.
First, the effect observed is small and if the distribution of four or five of the 823 outcomes of pregnancy had been different or distributed differently among the three groups, there would not be much to discuss or question.
