Nephron Clinical Practice, 2010 In confounding, the effect of the exposure of interest is mixed with the effect of another variable. It is important to identify relevant confounders and remove the confounding effect as much as possible. There are three criteria that need to be fulfilled to determine whether a variable could be considered a potential confounder. The first criterion is

Ethical review of real-world study
Реальная клиническая практика: данные и доказательства, 2022 This article is devoted to an ethical review of planned real-world studies. The legal basis of such examinations has also been considered. Most real-world studies are non-interventional, so the ethical review of such studies is similar to that of ...

Sensitivity analysis for causal effects with generalized linear models
Journal 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

Estimating the effect of healthcare-associated infections on excess length of hospital stay using inverse probability-weighted survival curves [PDF]
, 2020 Background: Studies estimating excess length of stay (LOS) attributable to nosocomial infections have failed to address time-varying confounding, likely leading to overestimation of their impact.

Understanding confounding effects in linguistic coordination: an information-theoretic approach [PDF]
, 2015 We suggest an information-theoretic approach for measuring stylistic coordination in dialogues. The proposed measure has a simple predictive interpretation and can account for various confounding factors through proper conditioning.

Confounding and confounders [PDF]
Occupational 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.
