When the risk ratio cannot be obtained directly (such as in a case-control study), the odds ratio is calculated and often interpreted as if it were the risk ratio. Subsequently, the term relative risk commonly
When the incidence of an outcome of interest is common in the study population (>10%), the adjusted odds ratio derived from the logistic regression can no longer approximate the risk ratio. The more frequent the outcome, the more the odds ratio overestimates the risk ratio ...
(this included prospective and retrospective cohort studies, nested case–control studies, case-cohort studies), (3) reported risk ratios (relative risk (RR), odds ratio (OR), hazard ratio (HR)) with corresponding 95% confidence intervals (CI) and 4) the papers were published following a ...
relative risk RR. Nested case-control and case-cohort studies – p.18/46 Odds-ratio from case-control studies However, the odds-ratio estimate OR is valid also in case-control studies. This is so because the case-control study allows estimation of the odds of exposure for cases and control...
In contrast, a case-control design focuses on the comparative exposure for those who have the condition relative to those without it. Do people with a condition have greater exposure? To answer this question, case-control studies typically report anodds ratio. ...

The advantages of a prospective observational cohort study are that a clear temporal relationship between exposure and disease is established, and the study may yield information about the length of induction (incubation) of the disease. Relative risk can be estimated directly. The design faci...
As odds ratios overestimate relative risk for outcomes that are common in the population under study (as falls were in our sample), relative risks were calculated directly where possible. Otherwise – for non-dichotomous variables and for multiple-variable models – relative risks were calculated ...
