For the next four years, this will be the conundrum: how to keep a press confounder from using press conferences to press confusion.

"We did not look at race-specific trends in this paper, although we did recognize race and ethnicity as a potential confounder," Ananth said.

For this image, Rowland mashed together an existing image of Zuckerberg with a photograph of a hired model—made up to look battered—whose features resembled that of the Facebook confounder and CEO.

However, education may be a confounder affecting both the father's attitude and the siblings' behavior, and the mother's attitudes did not have a noticeable impact.

Ovarian hyperstimulation does not seem to be associated with an elevated risk of cervical cancer, nor with ovarian cancer or endometrial cancer when neutralizing the confounder of infertility itself. Also, it does not seem to impact increased risk for breast cancer.

Among the fatal casualties was Bartolomé Cacobí, Hurons captain. At his court martial for the loss of Crafty, the court reprimanded Spencer for having failed to keep company with Confounder and for remaining too long at anchor in the bay.

In New Zealand, there is no correlation between lead exposure and socioeconomic status, thus social class does not act as a confounder. The authors conclude that "past studies of the association between BLL and crime, in which high BLL and low socioeconomic status were associated, may not have completely overcome confounding".

The difference of 0.6 children for both sexes was expected to decrease to between 0.2 and 0.3 over the lifetime when correcting for the confounder that married people have their children earlier in life. In the United States, those who cohabit without marrying had increased fertility when the male earns considerably more than the female.

After receiving several awards and working in Michelin-starred restaurants (La Table d'Anvers, Petrossian...), he is the confounder and head pastry chef of the Pâtisserie des Rêves, a patisserie with outlets in France, Japan and the UK. Very active in the media, Conticini appeared in the show Le Meilleur Pâtissier on French TV Channel M6 in 2012.

Mrs Gallay succeeded Ms at the head of the Association protestante de bienfaisance de Paris, which she presided from 1871 to 1892 (replaced by Ms de Neuflize).L'Exposition universelle de 1878 illustrée : publication internationale autorisée par la Commission. [chief editor: Jules Brunfaut] They were the grands-parents of , confounder and general secretary of the International Tennis Federation (whose daughter, tennis player , married ), and Marie-Antoinette Gallay, wife of general Charles Jordan.

Crafty was on her way with dispatches from the Dardanelles when she stopped at Gibraltar. She sailed from Gibraltar on 7 March in company with the gun-brig but the two vessels did not coordinate. Crafty carried too much sail and Confounder too little, with the result that they separated. The next day Crafty encountered gunvessels from the Algeciras flotilla and although she escaped, she had a gun dismounted.

Whereas a mediator is a factor in the causal chain (1), a confounder is a spurious factor incorrectly implying causation (2) In statistics, a spurious relationship or spurious correlationBurns, William C., "Spurious Correlations", 1997. is a mathematical relationship in which two or more events or variables are associated but not causally related, due to either coincidence or the presence of a certain third, unseen factor (referred to as a "common response variable", "confounding factor", or "lurking variable").

IVF does not seem to be associated with an elevated risk of cervical cancer, nor with ovarian cancer or endometrial cancer when neutralising the confounder of infertility itself. Nor does it seem to impart any increased risk for breast cancer. Regardless of pregnancy result, IVF treatment is usually stressful for patients. Neuroticism and the use of escapist coping strategies are associated with a higher degree of distress, while the presence of social support has a relieving effect.

Simpson's paradox can also arise in correlations, in which two variables appear to have (say) a positive correlation towards one another, when in fact they have a negative correlation, the reversal having been brought about by a "lurking" confounder. Berman et al.Berman, S. DalleMule, L. Greene, M., Lucker, J. (2012), "Simpson's Paradox: A Cautionary Tale in Advanced Analytics", Significance. give an example from economics, where a dataset suggests overall demand is positively correlated with price (that is, higher prices lead to more demand), in contradiction of expectation.

In causal models, controlling for a variable means binning data according to measured values of the variable. This is typically done so that the variable can no longer act as a confounder in, for example, in an observational study or experiment. When estimating the effect of explanatory variables on an outcome by regression, controlled-for variables are included as inputs in order to separate their effects from the explanatory variables. A limitation of controlling for variables is that back-door paths to unknown confounders may remain.

Bordo claims that "[w]hat remains the constant element throughout historical variation is the construction of body as something apart from the true self (whether conceived as soul, mind, spirit, will, creativity, freedom . . .) and as undermining the best efforts of that self".Bordo, Unbearable Weight, p. 5. She traces the "body" as a concept and as a material "thing" back to Plato, Augustine and the Bible revealing how traditionally the body has been viewed as "animal, as appetite, as deceiver, as prisoner of the soul and confounder of its projects".

Like other studies it examined later drug use differences between siblings where one sibling had used cannabis early and the other had not. The study examined identical twins (who share approximately 100% of their genes) and non-identical twins (who share approximately 50% of their genes) separately and adjusted for additional confounders such as peer drug use. It found, after confounder adjustment, that the associations with later hard drug use existed only for non-identical twins. This suggests a significant genetic factor in the likelihood of later hard drug usage.

Although childhood economic status may be seen as a confounder in the relationship between intelligence and mortality, as it is likely to affect intelligence, it is likely that adult SES mediates the relationship. The idea is that intelligent children will find themselves getting a better education, better jobs and will settle in a safer and healthier environment. They will have better access to health resources, good nutrition and will be less likely to experience the hazards and health risks associated with living in poorer neighbourhoods. Several studies have found that there is an association between adult SES and mortality.

The disadvantage of metabolomics is that it only provides the user with steady-state level information, while fluxomics determines the reaction rates of metabolic reactions and can trace metabolites in a biological system over time. Nutrigenomics is a generalised term which links genomics, transcriptomics, proteomics and metabolomics to human nutrition. In general a metabolome in a given body fluid is influenced by endogenous factors such as age, sex, body composition and genetics as well as underlying pathologies. The large bowel microflora are also a very significant potential confounder of metabolic profiles and could be classified as either an endogenous or exogenous factor.

Whereas a mediator is a factor in the causal chain (1), a confounder is a spurious factor incorrectly suggesting causation (2) Austin Bradford Hill built upon the work of Hume and Popper and suggested in his paper "The Environment and Disease: Association or Causation?" that aspects of an association such as strength, consistency, specificity, and temporality be considered in attempting to distinguish causal from noncausal associations in the epidemiological situation. (See Bradford- Hill criteria.) He did not note however, that temporality is the only necessary criterion among those aspects. Directed acyclic graphs (DAGs) are increasingly used in epidemiology to help enlighten causal thinking.

Regarding cohabitation as a fertility factor, a large survey in the United States came to the result that married women had an average of 1.9 children, compared to 1.3 among those cohabiting. The corresponding numbers for men were 1.7 and 1.1, respectively. The difference of 0.6 children for both sexes was expected to decrease to between 0.2 and 0.3 over the lifetime when correcting for the confounder that married people have their children earlier in life. A study of the United States and multiple countries in Europe came to the result that women who continue to cohabit after birth have significantly lower probability of having a second child than married women in all countries except those in Eastern Europe.

Conversely, an article published in BioMed Central has posited there is no evidence that being labeled with a single disorder leads to better treatment than being labeled with PTSD plus concurrent disorders. Complex PTSD embraces a wider range of symptoms relative to PTSD, specifically emphasizing problems of emotional regulation, negative self-concept, and interpersonal problems. Diagnosing complex PTSD can imply that this wider range of symptoms is caused by traumatic experiences, rather than acknowledging any pre-existing experiences of trauma which could lead to a higher risk of experiencing future traumas. It is also asserts that this wider range of symptoms and higher risk of traumatization are related by hidden confounder variables and there is no causal relationship between symptoms and trauma experiences.

Moreover, Philip Morris primarily funded the Meyer Friedman Institute, e.g. conducting the "crown- jewel" trial on the effectiveness of reducing TABP whose expected findings could discredit studies associating smoking with CHD and cancer but failing to control for Type A behaviour. In 1994, Friedman wrote to the US Occupational Safety and Health Administration criticising restrictions on indoor smoking to reduce CHD, claiming the evidence remained unreliable since it did not account for the significant confounder of Type A behaviour, notwithstanding the fact that by then, TABP had proven to be significant in only three of twelve studies. Though apparently unpaid for, this letter was approved by and blind- copied to Philip Morris, and Friedman (falsely) claimed to receive funding largely from the National Heart, Lung and Blood Institute.

A testimony to his conviction on the human safety of background low-level radiation was his offering rewards of up to $10,000 if people provided evidence that the inverse association he found between radon (county averages) and lung cancer (county averages) was due to some factor other than failure of the linear-no threshold theory. Puskin, Smith, Field and others have claimed that his findings are due in part to his inability to control for the inverse association between smoking and radon.Puskin, JL. Health Physics February 2004, Cohen, BL. "The Puskin observation on smoking as a confounder in ecological correlations of cancer mortality rates with average county radon levels", Health Phys 86:203–204; 2004 pp. 203–4.Radsafe A respectable end to radon debate needed Published email correspondence between Cohen and Vanderbilt University.
