Answer:

The odds ratio is commonly used to report the strength of association between exposure and an event. The larger the odds ratio, the more likely the event is to be found with exposure. The smaller the odds ratio is than 1, the less likely the event is to be found with exposure.

Is a higher odds ratio better or worse?

Answer: The magnitude of the odds ratio is called the “strength of the association.” The further away an odds ratio is from 1.0, the more likely it is that the relationship between the exposure and the disease is causal. For example, an odds ratio of 1.2 is above 1.0, but is not a strong association.

What does an odds ratio of 0.5 mean?

Answer: A RR of 0.5 means the risk is cut in half. But an OR of 3 doesn't mean the risk is threefold; rather the odds is threefold greater. Interpretation of an OR must be in terms of odds, not probability.

Why can you only use odds ratio in case control?

Answer: Incidence is Unknown in a Case-Control Study
In contrast, in a case-control study one can only calculate the odds ratio, i.e. an estimate of relative effect size, because one cannot calculate incidence. Consider once again the table that we used above to illustrate calculation of the odds ratio.

How do you explain odds ratio 1?

Answer: The odds ratio tells us how much higher the odds of exposure are among case-patients than among controls. An odds ratio of • 1.0 (or close to 1.0) indicates that the odds of exposure among case-patients are the same as, or similar to, the odds of exposure among controls. The exposure is not associated with the disease.
