Dear All
I was recently conversing with a colleague and the question of why use ORs
instead RRs came up. My naive response was that the choice seemed to be
based on the individual's preference and that I had not read anything that
suggested the use of one was more informative than another (and indeed have
read some material that suggests ORs are misleading when the OR is high -
but I don't want to get onto that issue).
Can anyone help me with why odds ratios might be used in preference to
relative risk or vice versa.
