RR or R.R., 1. railroad. 2. Right Reverend. 3. rural route.
RRR can also be expressed as: (The absolute risk) divided by (the probability of an event in the control group) However you calculate it, both groups show a RRR of 30%, i.e beta-blockade reduces the risk of a cardiac event by 30%, the corollary of the discussion under relative risk. For some diseases, the benefit a treatment offers remains constant even if the risk in the untreated group is not constant across different patient populations.
