Confounding [PDF]

open access: yesNephron Clinical Practice, 2010
In confounding, the effect of the exposure of interest is mixed with the effect of another variable.

Sensitivity analysis for causal effects with generalized linear models

open access: yesJournal of Causal Inference, 2022
Residual confounding is a common source of bias in observational studies. In this article, we build upon a series of sensitivity analyses methods for residual confounding developed by Brumback et al. and Chiba whose sensitivity parameters are constructed

Confounding and confounders [PDF]

open access: yesOccupational and Environmental Medicine, 2003
Confounding should always be addressed in studies concerned with causality. When present, it results in a biased estimate of the effect of exposure on disease. The bias can be negative - resulting in underestimation of the exposure effect - or positive, and can even reverse the apparent direction of effect.

Administrative data in pediatric critical care research—Potential, challenges, and future directions

open access: yesFrontiers in Pediatrics, 2022
Heterogenous patient populations with small case numbers constitute a relevant barrier to research in pediatric critical care. Prospective studies bring along logistic barriers and—if interventional—ethical concerns.

Levels of Evidence, Quality Assessment, and Risk of Bias: Evaluating the Internal Validity of Primary Research

open access: yesFrontiers in Veterinary Science, 2022
Clinical decisions in human and veterinary medicine should be based on the best available evidence. The results of primary research are an important component of that evidence base.
