Once we know the exposure and disease status of a research population, we can fill in their corresponding numbers in the following table. Definition Relative Risks (RR) are used to compare the risks of different groups. The parameter of interest is the relative risk or risk ratio in the population, RR=p 1 /p 2, and the point estimate is the RR obtained from our samples. The relative risk is a ratio and does not follow a normal distribution, regardless of the sample sizes in the comparison groups. The relative risks can be obtained from Gail Model, an unconditional logistic regression that included main effects NB_Cat, AM_Cat, AF_Cat, NR_Cat as well as interactions between AF_Cat and NR_Cat and between the age category and NR_Cat. In our case, an RR of 0.75 implies that there is a 25% (1 – 0.75 = 0.25) reduction in the relative risk of heart disease in the wine consuming group compared to the non-consuming group. Alternatively, we can say that the risk of heart disease in wine consumers is 0.75 times that of non-consumers.

This can be confusing because in our typical understanding of those terms, it makes no sense that a risk be … RR < 1: The risk in the exposed group is less than the risk in the unexposed group. So a person drinking wine has a smaller risk of having a heart disease relative to someone who does not drink red wine; In our case, an RR of 0.75 implies that there is a 25% (1 – 0.75 = 0.25) reduction in the relative risk of heart disease in the wine Risk ratios describe the multiplication of the risk that occurs with use of the experimental intervention. For example, a risk ratio of 3 for a treatment implies that events with treatment are three times more likely than events without treatment. Alternatively we can say that treatment increases the risk of events by 100 × (RR – 1)% = 200%. risk [risk] a danger or hazard; the probability of suffering harm. attributable risk the amount or proportion of incidence of disease or death (or risk of disease or death) in individuals exposed to a specific risk factor that can be attributed to exposure to that factor; the difference in the risk for unexposed versus exposed individuals. empiric risk Rr risk ratio.

Calculation. The RR is estimated as the absolute risk with the risk variable divided by the absolute risk in the control group. The group exposed to treatment (left) has the risk of an adverse outcome (black) reduced by 50% (RRR = 0.5) compared to the unexposed group (right). 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. 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. 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.
