Prenatal Paracetamol Exposure and Wheezing in Childhood: Causation or Confounding?
BACKGROUND Several studies have reported an increased risk of wheezing in the children of mothers who used paracetamol during pregnancy. We evaluated to what extent this association is explained by confounding. METHODS We investigated the association between maternal paracetamol use in the first and third trimester of pregnancy and ever wheezing or recurrent wheezing/asthma in infants in the ...
متن کاملWhy There Is No Statistical Test for Confounding, Why Many Think There Is, and Why They Are Almost Right
Confounding is a simple concept. If we undertake to estimate the e ect of one variable (X) on another (Y ) by examining the statistical association between the two, we ought to ensure that the association is not produced by factors other than the e ect under study. The presence of spurious association, due for example to the in uence of extraneous variables, is called confounding as it tends to...
متن کاملIllusory causation: why it occurs.
Considerable evidence indicates that people overattribute causality to a given stimulus when it is salient or the focus of their attention--the so-called illusory-causation phenomenon. Although illusory causation has proved to be quite robust and generalizable, a compelling explanation for it has not been empirically documented. Four social-attribution studies were conducted to test the hypothe...
متن کاملStatistical Models for Causation: A Critical Review
Regression models are often used to infer causation from association. For instance, Yule [79] showed – or tried to show – that welfare was a cause of poverty. Path models and structural equation models are later refinements of the technique. Besides Yule, examples to be discussed here include Blau and Duncan [12] on stratification, as well as Gibson [28] on the causes of McCarthyism. Strong ass...
متن کاملWhy Formal Methods Are Considered for Safety Critical Systems?
Formal methods are the mathematically techniques and tools which are used at early stages of software development lifecycle processes. The utter need of using formal methods in safety critical system leads to accuracy, consistency and correctness in proposed system. In safety critical real time application, requirements should be unambiguous and very accurate which can be achieved by using math...
