There is a calculator for this in Epi Info (available free from CDC) - it is in 'utilities' called 'stat-calc' in the version I have (3.3.2)

Do you know where I can find a simple calculator of OR and their 95% CI?
Catmaker doesn't return (OR and certainly not the CI of it) when comparing alternative therapies or therapy and control and looking at dichotomous outcomes.
Thanks
Martin
