The comments about the consistency with other studies in the conclusion were about the larger studies. When we talk about the larger studies, these were done by the Institute of Medicine, the National Research Council in the United States, and the Royal Society in Britain. Those were the three biggies, if you wish, the most authoritative, the most comprehensive.
We read them, obviously. We read some other articles, and some of the articles we read were the very same as those they had read. But those studies were done in 2001, 2004, and 2008. We looked at them, and we also looked at subsequent studies, and our conclusions concorded with those conclusions.
