Question

Answer 1

Attributable risk (AR) is the measurement of a widespreading ability of a disease or condition.Attributable risk provides the proportion of the disease incidence which can be potentially eliminated if exposure to the risk factor were prevented.It is also expressed as difference in incidence rates of disease or death between an exposed and non exposed group.

Attributable risk = Incidence of disease rate among susceptible - Incidence of disease rate among non vulnerable *100/ Incidence rate among susceptible

Risk difference is the difference between the incidence rate of disease in the susceptible group and the incidence rate of disease in the non vulnerable group.

Rate difference is the term  used as the measure of disease frequency and incidence of density measures . Rate difference is often  ratio comparing two rates .

As all the three terms are same. Attributable risk also called rate difference or risk difference.
