What does the odds ratio estimate in a case-control study ?
The use of the term « odds ratio » in reporting the findings of case-control studies is technically correct, but is often misleading.
The meaning of the odds ratio estimates obtained in a case-control study differs according to whether controls are selected from person-time at risk (the study base), persons at risk (the base-population at risk at the beginning of follow-up), or survivors (the population at risk at the end of follow-up).
These three methods of control selection correspond to estimating the rate ratio, risk ratio, or the odds ratio respectively, by means of calculating the odds ratio in the subjects actually studied.
None of these estimation procedures depends on any rare disease assumption.
