Which odds ratio is strongest?

What if odds ratio is 0?
If you have an infinite odds in the denominator, then your odds ratio is zero. Finally, if you have a zero odds in the denominator, then your odds ratio is infinite. The only case you can't handle is when both groups have 100% survival or 0% survival. This forces you to divide infinity by infinity or zero by zero.

Can you have an odds ratio of 0?
As odds of an event are always positive, the odds ratio is always positive and ranges from zero to very large. The relative risk is a ratio of probabilities of the event occurring in all exposed individuals versus the event occurring in all non-exposed individuals.
