Rick replies:

I agree with the quote. Unfortunately for those trying to understand what
happened here, there is an even more significant probablity that carbon
filtering was responsible.  In the paper, just before your quote, is a
statement of these probabilities.  In layman's terms, there is a
probability of only 0.014 that the association of illness and carbon filter
is due to chance.  In contrast, there is a probability of 0.04 that the
association of strain V and illness is due to chance.

About further study, Mardi Mellon said essentially the same thing and I
agree.  This is still a far cry from claiming that genetic engineering WAS
