Relative risk is calculated by dividing the death or disease risk in a specific population group (Group A) by the risk of people from all other groups. RR = Risk in One Group (Group A) Risk in All Other Groups What relative risk tells us A relative risk that is greater than 1.0 shows that there is an increased risk among the people in Group A. The relative risk (also called the risk ratio) of something happening is where you compare the odds for two groups against each other. For example, you could have two groups of women: one group has a mother, sister or daughter who has had breast cancer. The other group does not have any close female relatives who have had the disease. Relative Risk is calculated by dividing the probability of an event occurring for group 1 (A) divided by the probability of an event occurring for group 2 (B).

Relative risk (RR), also known as the risk ratio, is a ratio of proportions. Specifically, it is a ratio of Collectively, the equation for relative risk is. RR = [A/( A + B)] 

In epidemiology , the relative risk reduction (RRR) or efficacy is the relative decrease in the risk of an adverse event in the exposed group compared to an unexposed group. OR: 1 − risk ratio. In the first formula, the numerator (risk among unvaccinated − risk among vaccinated) is sometimes called the risk difference or excess risk. Vaccine efficacy/effectiveness is interpreted as the proportionate reduction in disease among the vaccinated group.

The formula for calculating relative risk … Relative risk is the ratio of the risk faced by one group to the risk faced by another group. This can be used to express the risk of a state, behavior or strategy as compared to a baseline risk. Calculation Relative risk is based on the probabilities of risk for two different groups as follows. The relative risk and the odds ratio are measures of association between exposure status and disease outcome in a population. Relative risk In epidemiology, relative risk (RR) can give us insights in how much more likely an exposed group is to develop a certain disease in comparison to a non-exposed group. Once we know the exposure and disease status of a research population, we can fill in • The relative risk reduction is the difference in event rates between two groups, expressed as a proportion of the event rate in the untreated group.
