Just to throw something into the mix you might want to look at -strel-
from the Cancer Survival Group at the London School of Hygeine &
Tropical Medicine.  Not sure if it allows adjusting for multiple

This reminds me of a quote thrown up by -njc- (see
http://pubpages.unh.edu/~rosem/stata/ )

"Waving newbieness at the list is like waving garlic at a vampire in old
horror films. It is, you may think, a little trick to protect yourself. In
newer horror films the vampires just laugh at garlic and bite you anyway.
In all films nice people are nice anyway and don't need pleas for gentleness"
