Invited commentary: understanding bias amplification.
In choosing covariates for adjustment or inclusion in propensity score analysis, researchers must weigh the benefit of reducing confounding bias carried by those covariates against the risk of amplifying residual bias carried by unmeasured confounders. The latter is characteristic of covariates that act like instrumental variables-that is, variables that are more strongly associated with the ex...
متن کاملInvited commentary: can selection bias explain the cardiovascular benefits of estrogen replacement therapy?
Evidence from over 30 epidemiologic studies indicates that postmenopausal women who take estrogen are at lower risk for coronary heart disease. A recent meta-analysis of all published studies found a 35 percent decrease in coronary disease (relative risk (RR) = 0.65, 95 percent confidence interval (CI) 0.60-0.70) for women who had ever used hormones compared with never users (1). Furthermore, t...
متن کاملSelection Bias
data in Haneuse et al. [1] . The risk ratio of dementia by exposure in the total target population is 2.0, and is the true association (there is no confounding in our simple DAG; fig. 1 ). Table 1 shows the expected distribution by exposure and outcome by strata of dead/alive under the following assumptions: half of the population dies; there is a risk ratio of death for the exposed compared to...
متن کاملInvited commentary: composite outcomes as an attempt to escape from selection bias and related paradoxes.
This commentary reviews the recent history of explanations to crossover paradoxes such as the birth weight and gestational age paradoxes, with a special emphasis on the current proposal by Kramer et al. in this issue of the Journal (Am J Epidemiol. 2014;179(3):361-367). We contend that the causal structure of these paradoxes is essentially identical to that of several well-known selection biase...
متن کاملInvited commentary: repeated measures, selection bias, and effect identification in neighborhood effect studies.
Research on neighborhood effects faces enormous methodological challenges, with selection bias being near the top of the list. In this issue of the Journal (Am J Epidemiol. 2014;180(8):776-784), Professor Jokela addresses this issue with novel repeated measures data and models that decompose putative effects into those within and between persons. His contribution shows that within-person neighb...
