Description: 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.
