The formula to calculate the Absolute Risk Increase (ARI) is:
\[ ARI = ART - ARC \]
Where:
Let's say the absolute risk of the treatment group (\( ART \)) is 0.15 and the absolute risk of the control group (\( ARC \)) is 0.10. Using the formula:
\[ ARI = 0.15 - 0.10 \]
We get:
\[ ARI = 0.05 \]
So, the Absolute Risk Increase (\( ARI \)) is 0.05.
Absolute Risk Increase (ARI) is a measure used to determine the increase in risk associated with a treatment or intervention compared to a control group. It is calculated by subtracting the absolute risk of the control group from the absolute risk of the treatment group. This metric is commonly used in clinical trials and medical research to assess the impact of treatments.
