Addressing comments above:

>Tony Floyd misleads by using the word "Found"

touche. I agree. 'Found' was too strong a word.

Perhaps the results of de Vincenzi's longitudinal study published in the New England Journal of Medicine(1) mean that she 'found' that:

---
"Consistent use of condoms for heterosexual intercourse is highly effective in preventing the transmission of HIV."
---

Have not Peter Flegg and myself found numerous reasons as to why the Padian study does not support alternative AIDS theories? Looking up articles by Gisselquist, Brody, Baldwin and others certainly indicates that these authors do not support anything out of the ordinary, as claimed above.

>Had he read the article by Gisselquist he would have understood that various assumptions were made to obtain the stated estimate

I was under no delusions here at all! Of course Gisselquist's estimate of 30% heterosexual transmission of HIV and his statement that 'most experts' suggest 90% heterosexual transmission involved certain assumptions by the parties involved.

Whether it is approximately 30%, approximately 90%, or approximately something in between, this would (as supported by de Vincenzi) still be a lot more than precisely zero.
