Relative Risk Reduction Formula. Relative risk reduction is a relative reduction in the overall business risks due to adverse circumstances of an entity which can be calculated by subtracting the Experimental event rate EER from the control event rate CER and dividing the resultant with the control event rate ER. RRR is usually constant across a range of absolute risks. Youll notice that were converting percentages to their decimal forms to carry out these calculations. R R A A B C C D displaystyle RRfrac AABCCD We can calculate relative risk using our example.
Relative risk is calculated as the absolute risk AR in the intervention groupdivided by the AR in the control group. Relative Risk Reduction RRR ARC - ART ARC x 100. Formula to Calculate Relative Risk Reduction. This video demonstrates 2 methods to calculate the commonly used measure to report outcomes in RCTs. But the ARR is higher and the NNT lower in people with higher absolute risks. Using the DCCT data this would work out to 0096 - 00280096 071 or 71.
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.
Relative Risk Reduction is calculated using the formula given below Relative Risk Reduction RRR Control Event Rate CER Experimental Event Rate EER Control Event Rate CER Relative Risk Reduction 20 15 20. Therefore an individual has a 10 chance of developing the disease with exposure absolute risk a 1 chance of developing the disease without exposure absolute risk and they are 10 times more likely to develop the disease if they have exposure relative risk. Relative Risk Reduction RRR ARC - ART ARC x 100. This video demonstrates 2 methods to calculate the commonly used measure to report outcomes in RCTs. Formula to Calculate Relative Risk Reduction.
