| number needed to treat |
a measure of treatment effect that providesthe number of patients who need to be treated to prevent one outcome event.It is the inverse of absolute risk reduction (l / absolute risk reduction);ie: l / ( P c - P t ). For instance, if the results ofa trial were that the probability of death in a control group was 25 % andthe probability of death in a treatment group was 10%, the number neededto treat would be 1 / (0.25 - 0.10) = 6.7 patients. ...
