I may Don, but no specific knowledge of numbers off hand. I come across so much stuff daily, hopefully I saved some or can find it in my computer history or references I have. There is not much comparison with HPV in the past, smoking/drinking vs non smoking/non drinking yes. Future studies or clinical trials have to include HPV status, I believe, and heard there a tissue bank where many samples are going to be banked for future reference.

I'm glad ChristineB posted the OCF link. I forget they exist. Actually, and sadly, I never read any of them, and probably will now, and would be helpful.

There is a recent report for HPV, I'll post on a separate link.
