WebAbstract. Background The potential impact fraction is a measure of effect that calculates the proportional change in disease risk after a change in the exposure of a related risk factor. Potential impact fractions are increasingly used to calculate attributable fractions when the lowest exposure is non-zero.

WebImpact Fraction. A generalization of the Attributable Fraction for the population that accommodates both hazardous and protective exposures, multiple levels of exposure, incomplete elimination of exposure, diffusion, or response to exposure. WebJan 18, 2024 · This estimate assumes that 100% of the exposed population could switch to clean fuels from polluting fuels. Population impact fractions (PIF) estimate potential improvements in mortality and burden of the disease under theoretical counterfactual scenarios that could reasonably be achieved in a population [51, 52].
