That's an interesting comment. Most people would argue the opposite: that
the odds ratio is misleading when the risks are not small. I believe there
are limitations to both the odds ratio and the relative risk. I have
documented my thoughts on the following web page.

Note in particular my comments relating the relative risk to the Car Talk
puzzler about the hundred pound sack of potatoes.
I'm curious what you think (both Rich Ulrich and other edstat-l readers)
about the interpretability of the odds ratio and the relative risk. I'd also
be interested in references about the intractability of the relative risk in
complex modeling situations.
