Re: Re: OR to RR

Thank you;but,am afraid that does not help me much. However;if a RR of less than 2 is considered not to be reliable or significant, and ORs give higher numbers,below what number is a OR considered to be not significant? Gary K.

Re: OR to RR

If the probabilities of the events are small enough for second order terms to be neglected, as they are here, the OR and RR may be considered equal; so the criterion applies in the same way.
The OR is just there for the purposes of obscurantism.
