Population impact fraction

WebThe population attributable fraction (PAF) is a useful measure for quantifying the impact of exposure to certain risk factors on a particular outcome at the population level. Recently, new model-based methods for the estimation of PAF and its con dence interval for di erent types of outcomes in a cohort study design have been proposed.
