Relative Risk Reduction = |EER-CER|/CER. In clinical studies it is important to look at both the absolute risk and the relative risk. For example, say the disease A

The following equation can be used to calculate the relative risk of two groups of people. R = [ a / (a+b)] / [c/(c+d))] Where R is the relative risk; a is the number of people in the exposed group with a disease; b is the number of people in the exposed group without the disease 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. change in the disease or outcome rate when compared to those without the exposure. Relative risk is a statistical measure of the strength of the association between a risk factor and an outcome. Relative risk can be calculated from a simple 2 X 2 table such as the one above.

## The formula for computing relative risk reduction is: (CER - EER)/CER. CER is the control group event rate and EER is the experimental group event rate.

R R = P ( D ∣ E ) P ( D ∣ ¬ E ) = P ( E ∣ D ) / P ( ¬ E ∣ D ) P ( E ) / P ( ¬ E ) . {\displaystyle RR= {\frac {P (D\mid E)} {P (D\mid eg E)}}= {\frac {P (E\mid D)/P ( eg E\mid D)} {P (E)/P ( eg E)}}.} The general formula for relative risk, using a 2x2 table, is: R R = A / ( A + B ) C ( / C + D ) {\displaystyle RR={\frac {A/(A+B)}{C(/C+D)}}} We can calculate relative risk using our example: Relative risk is a ratio of the probability of an event occurring in the exposed group versus the probability of the event occurring in the non-exposed group. Relative Risk is often used when the study involves comparing the likelihood, or chance, of an event occurring between two groups.

Where AR is the attributable risk; I e is the incidence rate in the exposed group Odds ratio vs.

Relative Risk (RR) is often used when the study involves comparing the likelihood, or chance, of an event occurring between two groups.

Here we discuss how to calculate Relative Risk Reduction with example, Calculator and downloadable excel An alternative way of calculating the relative risk reduction is to use the relative risk: RRR = (1 - RR). Use this term if the event is bad e.g. death.

whatapp. Many reports in the media about the benefits of treatments present risk results as relative Guide to Relative Risk Reduction Formula. Here we discuss how to calculate Relative Risk Reduction with example, Calculator and downloadable excel An alternative way of calculating the relative risk reduction is to use the relative risk: RRR = (1 - RR). Use this term if the event is bad e.g. death. Cross-sectional data may serve to calculate relative risks from prevalences. Cohort study designs allow for the direct calculation of relative risks from incidences.
