Risk, and related measures of effect size (for categorical outcomes) such as relative risks and odds ratios, are frequently presented in research articles. Not all readers know how these statistics are derived and interpreted, nor are all readers aware of their strengths and limitations. This article examines several measures, including absolute risk, attributable risk, attributable risk percen...

background: this is to assess one of the rare complications after total knee replacement and to assess risk factors of failure.methods: 11 patients with varus knee and an average age of 67 years underwent tka between 2005 and 2013. all patients returned with a sudden sharp knee pain, disability to walk and significant decrease in rom about 4 to 8 weeks after surgery. radiographic examination re...

Statistical methods for quantifying the population impact of exposure factors by means of estimating some variant of the attributable risk parameter for a binary disease variable based on stratification methods or multivariable models have been extensively developed during the last decade. In epidemiologic studies, these risk parameters enjoy growing popularityas they allow a practice-oriented ...

The attributable risk, often called the population attributable risk, is in many epidemiological contexts a more relevant measure of exposure-disease association than the excess risk, relative risk, or odds ratio. When estimating attributable risk with case-control data and a rare disease, we present a simple bias correction to the standard approach, which also makes it more stable and less var...

OBJECTIVE To examine the common clinical and behavioural factors that contribute to cardiovascular disease (CVD) risk (ie, attributable risk) among those with type 2 diabetes. DESIGN Analysis of data from a larger observational study. Using the validated UK Prospective Diabetes Study risk engine, the primary analysis examined the prevalence and attributable risk of CVD for 4 factors. Multivar...

background: water, sanitation and hygiene have a very important role in public health. poor sanitation is the cause of water contamination, which causes many types of diseases. the aim of this paper was to present the attributable death and disability adjusted life year (dalys) of untreated water and insanitary environments from 1990 to 2010 in iran.   methods: in the global burden of disease 2...

The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...
