Estimation and application of population attributable fraction in ecological studies [PDF]
Environmental Health, 2019 Estimation of population attributable fraction (PAF) requires unbiased relative risk (RR) by using either Levin’s or Miettinen’s formula, on which decision depends on the available exposure information in reference group, not the types of studies.

Prevalence of hyperuricemia and the population attributable fraction of modifiable risk factors: Evidence from a general population cohort in China. [PDF]
Front Public Health, 2022 Data on updated hyperuricemia prevalence in Beijing-Tianjin-Hebei (BTH) region in China, which is one of the world-class urban agglomerations, is sparse. Overweight/obesity, alcohol consumption, smoking and sedentary behavior are modifiable risk factors (

Causal inference with multi-state models - estimands and estimators of the population-attributable fraction [PDF]
Journal of the Royal Statistical Society: Series A (Statistics in Society), 2019 The population-attributable fraction (PAF) is a popular epidemiological measure for the burden of a harmful exposure within a population. It is often interpreted causally as proportion of preventable cases after an elimination of exposure.

The population-attributable fraction for time-dependent exposures using dynamic prediction and landmarking [PDF]
Biometrical journal. Biometrische Zeitschrift, 2019 The public health impact of a harmful exposure can be quantified by the population-attributable fraction (PAF). The PAF describes the attributable risk due to an exposure and is often interpreted as the proportion of preventable cases if the exposure ...

The population-attributable fraction for time-dependent exposures and competing risks - A discussion on estimands [PDF]
Statistics in Medicine, 2019 The population-attributable fraction (PAF) quantifies the public health impact of a harmful exposure. Despite being a measure of significant importance an estimand accommodating complicated time-to-event data is not clearly defined.

What Does the Population Attributable Fraction Mean?
Preventing Chronic Disease, 2007 Recent controversy over the disagreement of population attributable fraction estimates for the obesity–total mortality relation has made the concept of attributable fraction visible in both scientific and popular news.
