Posted by Dinesh on**Attributable risk** is helpful in showing to what extent the exposure to the variable of interest relates to the outcome studied.

To calculate **attributable risk**, Subtract the outcome incidence rate of the control group from the outcome incidence rate of the experimental group.

`Attributable risk = (a-c)`
