Other Comments

An informal review of points to consider was submitted to RADA on April 6, 2004.

Summary of this informal review:
"In short, the tiny sample size was inadequate to produce any findings of statistical significance. The writers' inability to calculate simple percentages seems to explain their failure to recognize the statistical insignificance of their results."

A growing list of points to consider was submitted to RADA on April 5, 2004.

Summary of this list of points:
The Journal of American Public Health "...might like to introduce proper 'peer review' of articles before they publish them, as most good scientific journals do. At least I assume they don't at present because anyone with some basic scientific training would see that this article is misleading because the person who wrote it clearly does not have any understanding of 'confidence limits' and basic statistics."
