WebSo a ratio of 1.0 for either the odds ratio or the relative risk implies perfect similarity between the two groups. Deviations from 1.0 imply dissimilarity between the two groups. The more the ratio deviates from 1.0, the greater the dissimilarity. It is important, however, to remember that ratios are skewed measures; deviations less than 1.0 ... WebFeb 1, 2008 · Odds ratio is similar to relative risk. In the sheepskin trial the relative risk was 0.58 and the odds ratio was 0.54. For most clinical trials where the event rate is low, that is less than 10% of all participants have an event, the odds ratio and relative risk can be considered interchangeable.

WebThe Mantel-Haenszel method, in contrast, reports hazard ratios that are further from 1.0 (so the reported hazard ratio is too large when the hazard ratio is greater than 1.0, and too small when the hazard ratio is less than 1.0). They did not test the two methods with data simulated where the assumption of proportional hazards is not true. WebWe would do this by swapping the comparison and recalculating the risk ratio: RR Dropouts/Graduates = .75/.56 = 1.33. Here we conclude that dropouts are 33% more likely than graduates to be convicted of a felony. Some references will advise re-coding the data so that the relative risk is always greater than 1.
