1. The difference in event rates between two groups expressed as a proportion of the event rate in the untreated group. The RRR may be similar in populations with different risks. An estimate of the number of people spared the consequences of an exposure that has been eliminated or controlled. The amount by which a person’s risk of disease is reduced by elimination or control of an exposure to risk....
