What research is being done on osteoporosis? Khosla and other osteoporosis researchers are studying new imaging and computer techniques that will allow them to look inside the bone, and see specific structural characteristics. This will help them to build models of bone strength that can help predict which patients are most likely to have fractures. […]

Why is confounding important?
Why is confounding important? Confounding is an important concept in epidemiology, because, if present, it can cause an over- or under- estimate of the observed association between exposure and health outcome. The distortion introduced by a confounding factor can be large, and it can even change the apparent direction of an effect. Why is confounding […]
What are confounders in a research study?
What are confounders in a research study? A Confounder is an extraneous variable whose presence affects the variables being studied so that the results do not reflect the actual relationship between the variables under study. The aim of major epidemiological studies is to search for the causes of diseases, based on associations with various risk […]
What is confounding in a study?
What is confounding in a study? Confounding is often referred to as a “mixing of effects”1,2 wherein the effects of the exposure under study on a given outcome are mixed in with the effects of an additional factor (or set of factors) resulting in a distortion of the true relationship. How is confounding controlled in […]

What are the key characteristics of a confounding variable?
What are the key characteristics of a confounding variable? Confounding variables are those that may compete with the exposure of interest (eg, treatment) in explaining the outcome of a study. The amount of association “above and beyond” that which can be explained by confounding factors provides a more appropriate estimate of the true association which […]
What is the difference between bias and confounding?
What is the difference between bias and confounding? Bias creates an association that is not true, but confounding describes an association that is true, but potentially misleading. What is meant by confounding? Confounding in a study occurs when the effects of two or more explanatory variables are not separated. Therefore, any relation that may […]
