Population Attributable Risk (PAR) is the porportion of the incidence of a disease in the population (exposed and nonexposed) that is due to exposure. PAR is the difference between the risk in the total population and that in unexposed subjects.

Accordingly, this article aims to provide an educational tutorial/topic primer on some of the most ubiquitous measures of association and risk quantification in medical research, including odds ratios, relative risk, absolute risk, and number needed to treat, using several real-world examples from the medical literature.

Calculate the attributable risks to assess the fraction and portion of the risk due to exposure and predict the impact on the incidence of disease when a causal risk factor is removed

2009年10月8日 · Population attributable risk (PAR) or etiologic fraction is the proportion of a disease that could be prevented by elimination of a causal risk factor from the population. PAR is likely to be a function of time because both the prevalence of a risk factor and its effect on exposed individuals

Attributable risk (AR) is the portion of disease rate attributable to the exposure factor in the epidemiologic context, the portion of correct diagnosis rate attributable to a positive predictive result (e.g., lab test) in the clinical context, or the portion of beneficial outcome rate attributable to a treatment. The AR of 0.266 in the dust ...

We present methods for obtaining point and interval estimates of the PAR and the partial PAR (pPAR) in the presence of misclassification, filling an important existing gap in public health evaluation methods.

2025年2月3日 · Background The incidence and mortality rates of pancreatic cancer are rising globally. This study examines global and regional trends in pancreatic cancer incidence, Disability Adjusted Life Years (DALYs), and mortality from 1990 to 2021, utilizing data from the most recent Global Burden of Disease (GBD) 2021 database. Methods Data were sourced from the GBD database over the period from 1990 ...

2025年2月24日 · Data from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021 provide critical insights that can guide the understanding and management of these cancers. Our study aims to offer comprehensive global, regional, and national estimates of the FBCUO cancer burden and its attributable risk factors from 1990 to 2021, as well as ...

The attributable proportion, also known as the attributable risk percent, is a measure of the public health impact of a causative factor. The calculation of this measure assumes that the occurrence of disease in the unexposed group represents the baseline or expected risk for that disease.
