Why is odds ratio exaggerated?

The odds ratio will always overstate the case when interpreted as a relative risk, and the degree of overstatement will increase as both the initial risk increases and the size of any treatment effect increases.

What if odds ratio is greater than 1?

Greater than 1.0 indicates that the odds of exposure among case-patients are greater than the odds of exposure among controls. The exposure might be a risk factor for the disease. Less than 1.0 indicates that the odds of exposure among case-patients are lower than the odds of exposure among controls.

What happens if odds ratio crosses 1?

Most studies report the 95% confidence interval (95%CI). If the confidence interval crosses 1 (e.g. 95%CI 0.9-1.1) this implies there is no difference between arms of the study.

What is the difference between odds and likelihood?

Odds is the chance of an event occurring against the event not occurring. Likelihood is the probability of a set of parameters being supported by the data in hand. In logistic regression, we use log odds to convert a probability-based model to a likelihood-based model.
