In epidemiology, a risk factor or determinant is a variable associated with an increased risk of disease or infection. [ 1 ] : 38 Due to a lack of harmonization across disciplines, determinant , in its more widely accepted scientific meaning , is often used as a synonym.
Host factor (sometimes known as risk factor) [1] is a medical term referring to the traits of an individual person or animal that affect susceptibility to disease, especially in comparison to other individuals. [2]
RR < 1 means that the risk of the outcome is decreased by the exposure, which is a "protective factor" RR > 1 means that the risk of the outcome is increased by the exposure, which is a "risk factor" As always, correlation does not mean causation; the causation could be reversed, or they could both be caused by a common confounding variable ...
Attributable fraction for the population combines both the relative risk of an incident with respect to the factor, as well as the prevalence of the factor in the population. Values of AF p close to 1 indicate that both the relative risk is high, and that the risk factor is prevalent. In such case, removal of the risk factor will greatly reduce ...
For example, a risk of 9 out of 10 will usually be considered as "high risk", but a risk of 7 out of 10 can be considered either "high risk" or "medium risk" depending on context. The definition of the intervals is on right open-ended intervals but can be equivalently defined using left open-ended intervals ( τ j − 1 , τ j ] {\displaystyle ...
Factor Analysis of Information Risk (FAIR) is devoted to the analysis of different factors influencing IT risk.It decompose at various levels, starting from the first level Loss Event Frequency and Probable Loss Magnitude, going on examining the asset, the threat agent capability compared to the vulnerability (computing) and the security control (also called countermeasure) strength, the ...
In finance, risk factors are the building blocks of investing, that help explain the systematic returns in equity market, and the possibility of losing money in investments or business adventures. [ 1 ] [ 2 ] A risk factor is a concept in finance theory such as the capital asset pricing model , arbitrage pricing theory and other theories that ...
The risk difference (RD), excess risk, or attributable risk [1] is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as I e − I u {\displaystyle I_{e}-I_{u}} , where I e {\displaystyle I_{e}} is the incidence in the exposed group, and I u {\displaystyle I_{u}} is the incidence in the ...
