Why is attributable risk important?
Also to know is, what does attributable risk tell us?
The Attributable Risk (AR) Measures of impact, such as attributable risks, measure how much of the trait would be prevented were it removed from the population. Attributable Risk (AR) is the difference in the disease rates in exposed and unexposed individuals.
Also Know, how do you interpret attributable risk? Attributable Risk and Attributable Risk Percent To calculate the attributable risk, one simply subtracts the risk for the non-exposed group from the risk for the exposed group. Thus, attributable risk is sometimes called the Risk Difference, or Excess Risk. The excess risk is “attributed” to the exposure.
Then, what does attributable risk mean?
Attributable Risk(AR) (sometimes called Attributable Proportion or Attributable Fraction) is a measure of the prevalence of a condition or disease. Given a group of people exposed to a risk, it's the fraction who develop a disease or condition.
What is the difference between relative risk and attributable risk?
Relative risk estimates the magnitude of an association between exposure and disease, based on the incidence of disease in the exposed group relative to the unexposed group. Attributable risk, or risk difference, is the absolute difference in incidence between an exposed and unexposed group.
