WebFor outcome probabilities specified to lie in symmetric intervals centered around 0.5, it is shown that the square-root transformation of the odds ratio is the optimal minimax conversion for the risk ratio. General results for any nonsymmetric interval are given both for odds ratio and for hazard ratio conversions. WebThe prevalence indicator is preferred to incidence when measuring chronic diseases which are characterised by a long duration and difficulty in pointing out the exact date of onset. Prevalence is usually reported as a percentage, but may also be found as no out of 100 or as number of cases per 10,000 or 100,000 people.

WebAn odds ratio is the odds of the event in one group, for example, those exposed to a drug, divided by the odds in another group not exposed. Odds ratios always exaggerate the true relative risk to some degree. When the probability of the disease is low (for example, less than 10%), the odds ratio approximates the true relative risk. WebThis Relative Risk and Odds Ratio calculator allows you to determine the comparative risk of the occurrence of a significant event (or outcome) for two groups.
