The term attributable risk is also known as the rate difference or risk difference.

Question

BlackTom AI · Accepted Answer

The question asks about whether the term attributable risk is also known as the rate difference or risk difference.
Option 1: True. Attributable risk (AR) is defined as the difference in incidence (or risk) of a disease between the exposed group and the unexposed group: AR = Risk_exposed − Risk_unexposed. This numerical difference represents the amount of risk that can be attributed to the exposure, which aligns with the concept of a rate difference or risk difference.
Option 2: False. This would be incorrect because, in epidemiology, attributable risk is precisely the difference in risk between two groups and is commonly referred to as the risk difference or rate difference; it is not a separate, unrelated concept. Saying it is not a rate difference would ignore the standard definition and nomenclature that connect AR to the absolute difference in incidence rates between groups.
Overall, the statement aligns with standard definitions: attributable risk corresponds to the risk difference (rate difference) between exposed and unexposed groups.
