I take what this guy writes on statistics with a large grain of salt; despite the domain name the author is not an economist. He is an MD and it goes without saying that he's very smart and accomplished -- but not in the field of statistics. This is relevant to this particular article, because he may be missing subtle, but important factors that a lay-person would miss. For example, see yummyfajita's post in this discussion.
