Can an odd ratio be as low as <0.001?

With a 95% CI of <0.001 to >999.999? Any idea what could be wrong?

(Sorry about the french output, will gladly provide more info if needed)

Thanks a lot!



Less is more. Stay pure. Stay poor.
This is likely related to complete separation of data, meaning that the predictor almost perfectly explains the outcome.

You can explore this by creating a 2x2 table of variable and outcome.
