Population attributable risk is defined as:-
Population Attributable Risk (PAR) It is the incidence of disease (or death) in total population minus incidence of disease (or death) among those who were not exposed to suspected causal factor. It is useful as it provides an estimation of amount by which incidence of disease could be reduced in that population if the suspected factor was eliminated or modified. PAR is useful for National health programmes and policies.
Incidence of disease among exposed is so many times higher as compared to that among non-exposed
So much disease can be attributed to exposure
If risk factor is modified or eliminated, there will be so much annual reduction in incidence of disease in the given population
None of the above
