Overadjustment bias and unnecessary adjustment in epidemiologic studies
Overadjustment is defined inconsistently. This term is meant to describe control (eg, by
regression adjustment, stratification, or restriction) for a variable that either increases net …

Bounding bias due to selection
LH Smith, TJ VanderWeele - Epidemiology, 2019 - journals.lww.com
When epidemiologic studies are conducted in a subset of the population, selection bias can

Statistical foundations for model-based adjustments
S Greenland, N Pearce - Annual review of public health, 2015 - annualreviews.org
Most epidemiology textbooks that discuss models are vague on details of model selection.
This lack of detail may be understandable since selection should be strongly influenced by …

On the pitfalls of adjusting for gestational age at birth
Preterm delivery is a powerful predictor of newborn morbidity and mortality. Such problems
