Certain types of trial designs, however, report risk as an odds ratio. This format is commonly expressed in cohort studies using logistic regression. Both the odds ratio and the relative risk compare the relative likelihood of an event occurring between two groups. The relative risk is easier to interpret and is consistent with general intuition. Some designs, however, allow only for the calculation of the odds ration. Covariate adjustment is eas … Since relative risk is a more intuitive measure of effectiveness, the distinction is important especially in cases of medium to high probabilities.

For both measures a value of 1 indicates that the estimated effects are the same for both interventions. Neither the risk ratio nor the odds ratio can be calculated for a study Risk Ratio (RR) = 27/300 ÷ 108/320 = 0.267 Odds ratio (OR) = (27x 212) ÷ (273 x 108) = 0.194 Relative Risk Reduction (RRR) = 0.248 ÷ 108/320 = 0.735 Relative risk of reduction of migraine = 73.5% NNT = 1/ARR = 4.03 = number of patients who need to be treated to prevent 1 additional migraine Relative Risk and Odds Ratio for the obese: 3) Overall, you can see that decreasing the baseline incidence will decrease the odds ratio (3.00 in those who are non-obese versus 1.29 in those who are obese).

If this baseline risk is high, then a relative risk of 5 would be alarming; if the baseline risk is small, then a relative risk of 5 may not be too serious. For instance, if the risk of a heart attack for someone in the normal range was 1 out of 10, then the risk of a heart attack for a person with the above average numbers would be five times this or 5 out of 10.

Odds Ratio (OR) för lungcancer hos rökare respektive f.d. rökare bland män och Om den relativa risken för lungcancer hos asbestexponerade individer är

The basic difference is that the odds ratio is a ratio of two odds (yep, it’s that obvious) whereas the relative risk is a ratio of two probabilities (the relative risk is also called the risk ratio). Relative Risk (RR) is a ratio of probabilities or put another way it is one probability divided by another. Odds Ratio (OR) is a ratio or proportion of odds.

Let us now look at the relation between the relative risk and the odds ratio (Zhang and Yu, 1998). OR= ˇ 1 1 1ˇ 1 ˇ 2 1 ˇ 2 = ˇ ˇ 2 1 2 1 1 = RR 2 1 (2.1) From this we see that OR is always further away from 1 than RR. But, more im-portantly, we see that the odds ratio is close to the relative risk if probabilities of the outcome are small (Davies et al., 1998).
