The value of the difference between the probability that an event will occur in the group exposed to a given factor and the probability that this event will occur in the group not exposed to this factor.
Note: For example, if the results of a trial were that the probability of death was 25% in the control group and 10% in the experimental group, the absolute risk reduction would be 0.25 – 0.10 = 0.15.
Syn.: Absolute risk reduction
