Absolute risk reduction is a term used to describe the reduction in risk of a particular event or outcome due to an experimental treatment. It is the difference in the risk of the event or outcome between the treatment group and the control group. For example, if the risk of a heart attack in the control group is 10%, and the risk of a heart attack in the treatment group is 5%, then the absolute risk reduction would be 5%.
Relative risk reduction (A) is the proportional reduction in risk between the treatment group and the control group. It is calculated as the difference in risk between the two groups divided by the risk in the control group. Number needed to treat (B) is the number of people who need to receive a treatment in order for one person to benefit from the treatment. Control event rate (C) is the proportion of participants in the control group who experience the event or outcome being studied.
