Relative Risk Reduction Calculator
The relative risk reduction (rrr) is a amount that can be obtained by dividing the absolute risk reduction by the control event rate.

Formula:
RRR = (EER - CER) /CER
EER = EE / ES
ES = EE + EN
CER = CE / CS
CS = CE + CN
Where,
RRR = Relative Risk Reduction
[ if (r is negative, then it is Relative Risk Reduction),
if (r is positive, then it is Relative Risk Increase) ]
EER = Experimental Event Rate
CER =Control Group Event Rate
EE = Experimental Events
EN = Experimental Non Events
ES = Experimental Total Subjects
CE = Control Group Events
CN = Control Group Non Events
CS = Control Group Total Subjects
