What does odds ratio of 1 mean?
An odds ratio of 1 indicates that the condition or event under study is equally likely to occur in both groups. An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group.

Frequently Asked Questions
How do you interpret less than 1 odds ratio?
This is often a risk factor. Odds Ratio < 1: The numerator is less than the denominator. Hence, the probability of the outcome occurring is lower for the group/condition in the numerator. This can be a protective factor.
How do you interpret 1.5 odds ratio?
If something has a 25% chance of happening, the odds are 1:3. You interpret an odds ratio the same way you interpret a risk ratio. An odds ratio of 1.5 means the odds of the outcome in group A happening are one and a half times the odds of the outcome happening in group B.
What is an odds ratio of less than 1?
Definition in terms of group-wise odds
An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group. And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group. The odds ratio must be nonnegative if it is defined.
What if odds ratio is less than 1?
And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group. The odds ratio must be nonnegative if it is defined.
What does an odds ratio of .2 mean?
An OR of 0.2 means there is an 80% decrease in the odds of an outcome with a given exposure.
What is a 0.1 odds ratio?
1:10
For example, when the odds are 1:10, or 0.1, one person will have the event for every 10 who do not, and, using the formula, the risk of the event is 0.1/(1+0.1) = 0.091. In a sample of 100, about 9 individuals will have the event and 91 will not.
How do you interpret 0.25 odds ratio?
The OR of 0.25 means that the odds of developing influence are 25% as high (or 75% lower) for the treatment group compared to the placebo group.
What does an odds ratio of 1.01 mean?
An odds ratio greater than 1 implies there are greater odds of the event happening in the exposed versus the non-exposed group. An odds ratio of less than 1 implies the odds of the event happening in the exposed group are less than in the non-exposed group.
What if odds ratio is more than 1?
An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group. And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group. The odds ratio must be nonnegative if it is defined.
How do you interpret a negative odds ratio?
Positive odds ratios indicate that the event is more likely to occur, whilst negative odd ratios indicate the event is less likely to occur. Note that the coefficient is the log odds ratio.
What does a risk ratio of 1 mean?
No difference in risk
A risk ratio of 1.0 indicates there is no difference in risk between the exposed and unexposed group. A risk ratio greater than 1.0 indicates a positive association, or increased risk for developing the health outcome in the exposed group.
What does an odds ratio of 0.98 mean?
The reported odd ratio of 0.98 at less than 1 indicates that for every additional parameter of the tested independent variable, they were . 98 times likely to report the likelihood of the test question. The p value of . 003 is statistically significant.
What does an odds ratio of 0.90 mean?
0.9 or 90% tells us the amount or the percentage of odds respectively that the result is lower compared to the control (In the above 7.7 was higher). Our interpretation takes a similar shape – The odds of disease risk awareness among people who are sick is 90% lower compared to the odds of people who are healthy. (
What does an odds ratio of 0.70 mean?
If the Odds ratio is 0.7 then it indicates a protective effect - I.e a reduced odds of exposure in case vs control group. That reduced risk is 1-odds so will be 30 percent reduced risk fo exposure. statistical significance is linked to the p-value or CI- which we cannot infer from only the odds ratio.
FAQ
- What does an odds ratio of .75 mean?
- "When you are interpreting an odds ratio (or any ratio for that matter), it is often helpful to look at how much it deviates from 1. So, for example, an odds ratio of 0.75 means that in one group the outcome is 25% less likely. An odds ratio of 1.33 means that in one group the outcome is 33% more likely."
- What does risk ratio less than 1 mean?
- Assuming there are no other factors that may confound the association, a risk ratio less than 1 indicates that the risk in the exposed (index) group is less than the risk in the unexposed or less -exposed (reference) group, and therefore, the exposure is preventive.
- What does a negative odds ratio mean?
- A negative odds ratio indicates that the odds of the event occurring are lower in the exposed group compared to the unex. Bob Chamberlain. Eagle Scout, Caltech grad, 53 yrs at JPL (ret), agnostic Author has 386 answers and 319K answer views 3y.

- What does an odds ratio of 1.5 mean?
- As an example, if the odds ratio is 1.5, the odds of disease after being exposed are 1.5 times greater than the odds of disease if you were not exposed another way to think of it is that there is a 50% increase in the odds of disease if you are exposed.
- What does a risk ratio of 0.5 mean?
- For example, when the RR is 2.0 the chance of a bad outcome is twice as likely to occur with the treatment as without it, whereas an RR of 0.5 means that the chance of a bad outcome is twice as likely to occur without the intervention. When the RR is exactly 1, the risk is unchanged.
- How do you interpret binary logistic regression results?

- An odds ratio of less than 1 implies the odds of the event happening in the exposed group are less than in the non-exposed group. An odds ratio of exactly 1 means the odds of the event happening are the exact same in the exposed versus the non-exposed group.
- Is a higher OR lower odds ratio better?
- Odds Ratio is a measure of the strength of association with an exposure and an outcome. OR > 1 means greater odds of association with the exposure and outcome. OR = 1 means there is no association between exposure and outcome. OR < 1 means there is a lower odds of association between the exposure and outcome.
- Does odds ratio tell you risk?
- The odds ratio (OR) is the ratio of odds of an event in one group versus the odds of the event in the other group. An RR (or OR) of 1.0 indicates that there is no difference in risk (or odds) between the groups being compared.
- How do you interpret risk ratio less than 1?
- Assuming there are no other factors that may confound the association, a risk ratio less than 1 indicates that the risk in the exposed (index) group is less than the risk in the unexposed or less -exposed (reference) group, and therefore, the exposure is preventive.
- What does an odds ratio of 2.5 mean?
- For example, OR = 2.50 could be interpreted as the first group having “150% greater odds than” or “2.5 times the odds of” the second group.
- How to interpret odds ratio less than 1 for categorical variables?
- The interpretation of the odds ratio depends on whether the predictor is categorical or continuous.

- How do you interpret 0.2 odds ratio?
- An odds of 0.2 however seems less intuitive: 0.2 people will experience the event for every one that does not. This translates to one event for every five non-events (a risk of one in six or 17%).
- What does a 0.1 odds ratio mean?
- The simplest way to ensure that the interpretation is correct is to first convert the odds into a risk. For example, when the odds are 1:10, or 0.1, one person will have the event for every 10 who do not, and, using the formula, the risk of the event is 0.1/(1+0.1) = 0.091.
