What risk ratio means?
A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group.
What does a risk ratio of 1.5 mean?
A risk ratio greater than 1.0 indicates a positive association, or increased risk for developing the health outcome in the exposed group. A risk ratio of 1.5 indicates that the exposed group has 1.5 times the risk of having the outcome as compared to the unexposed group.
What does a risk ratio of 0.8 mean?
A relative risk that is less than 1.0 indicates that there is a lower risk among the people in Group A. • If the relative risk were 0.8, people in Group A would be 20% less likely than people in all other groups to die from a cause.
What does a risk ratio of 1.2 mean?
The magnitude of the odds ratio is called the strength of the association. The further away an odds ratio is from 1.0, the more likely it is that the relationship between the exposure and the disease is causal. For example, an odds ratio of 1.2 is above 1.0, but is not a strong association.
