selection bias in case-control studies case-control study:一种研究变量间关系的试验方法。简单说就是根据产生目标的结果选择treatment组(比如肺癌患者),然后再选择没有结果的人(未得肺癌)作为control组,然后比较他们的一些解释变量(自变量)方法。(一种回溯(retrospection)的方法) 选择的control组不能代表产生结果的人...
selection bias in cohort studies cohort studies:也是一种研究变量间关系的试验方法。选择一群人在一段时间具有相似的特征,然后观测他们时候会发生某些结果。相对case-control,它可以是回溯过去 (retrospective) 也可以是预期未来(prospective),且可以不需要对照组。下图简单对比了两个方法。 case-control vs. cohort (...
Time-related biases in cohort studies can produce illusory "beneficial" effects of medications due entirely to an artifact of the analytic design. We describe "time-window bias" in the context of a case-control study, reporting that statin use was associated with a 45% reduction in the inciden...

It has recently been shown that the bias due to misclassification of a binary exposure in case-control studies can be simply expressed in terms of so-called quality indices. Quality indices are measures of the degree of misclassification that are symmetric with respect to the true and measured ...
As a result, we can distill prediction studies into a common structure (Fig.1): the members of the diseased population begin as controls at a point in the past, and progress along a trajectory until the disease occurs. Most case-control studies apply a dichotomous framework over this continuo...
The properties of these antidotes/tests are described and located in both accounting and a wider literature. The characteristics of each antidote are further considered, and the adverse consequences of the failure to apply them are illustrated through analysis of a number of case-studies by leading...
Sex bias of experimental animals in MIA studies—overview For the present analysis studies reporting behavioral, cytokine, and neurotransmitter offspring phenotypes in MIA animal models, were collected by literature search (key words have: “maternal immune activation AND behaviors”; “maternal immune ac...
