Journal ArticleDOI
Causal diagrams for epidemiologic research.
TL;DR: Causal diagrams can provide a starting point for identifying variables that must be measured and controlled to obtain unconfounded effect estimates and provide a method for critical evaluation of traditional epidemiologic criteria for confounding.
Journal ArticleDOI
The impact of confounder selection criteria on effect estimation
Ruth M. Mickey,Sander Greenland +1 more
TL;DR: The results of a Monte Carlo simulation of several confounder selection criteria, including change-in-estimate and collapsibility test criteria, are presented, compared with respect to their impact on inferences regarding the study factor's effect.
Journal ArticleDOI
Simulation Study of Confounder-Selection Strategies
TL;DR: The authors compared the performance of several such strategies for fitting multiplicative Poisson regression models to cohort data, finding that the change-in-estimate and equivalence-test-of-the-difference strategies performed best when the cut-point for deciding whether crude and adjusted estimates differed by an important amount was set to a low value.
Journal ArticleDOI
Modeling and variable selection in epidemiologic analysis.
TL;DR: An overview of problems in multivariate modeling of epidemiologic data is provided, and some proposed solutions are examined, including model and variable forms should be selected based on regression diagnostic procedures, in addition to goodness-of-fit tests.
