An Instrumental Variable Analysis Comparing Medicare Expenditures for Laparoscopic vs Open Colectomy
Sign Up to like & getrecommendations! Published in 2017 at "JAMA Surgery"
DOI: 10.1001/jamasurg.2017.1578
Abstract: Importance Numerous study findings suggest that the use of laparoscopy is associated with lower health care costs for many operations, including colectomy. The extent to which these differences are due to the laparoscopic approach itself… read more here.

Adjusting for collider bias in genetic association studies using instrumental variable methods
Sign Up to like & getrecommendations! Published in 2022 at "Genetic Epidemiology"
DOI: 10.1002/gepi.22455
Abstract: Genome‐wide association studies have provided many genetic markers that can be used as instrumental variables to adjust for confounding in epidemiological studies. Recently, the principle has been applied to other forms of bias in observational… read more here.

DOI: 10.1002/sim.8071
Abstract: Instrumental variable is an essential tool for addressing unmeasured confounding in observational studies. Two-stage predictor substitution (2SPS) estimator and two-stage residual inclusion (2SRI) are two commonly used approaches in applying instrumental variables. Recently, 2SPS was… read more here.

DOI: 10.1002/sim.8730
Abstract: Instrumental variable (IV) analysis can be used to address bias due to unobserved confounding when estimating the causal effect of a treatment on an outcome of interest. However, if a proposed IV is correlated with… read more here.

DOI: 10.1007/s10654-019-00578-3
Abstract: In recent years, epidemiologists have increasingly sought to employ genetic data to identify ‘causal’ relationships between exposures of interest and various endpoints – an instrumental variable approach sometimes termed Mendelian randomization. However, this approach is… read more here.

DOI: 10.1007/s40313-016-0285-8
Abstract: In this paper, an online identification algorithm for instrumental variable-based evolving neuro-fuzzy modeling applied to dynamic systems in noisy environment is proposed. The adopted methodology is based on neuro-fuzzy inference system with Takagi–Sugeno evolving structure,… read more here.

Inferring Causality from Observational Studies: The Role of Instrumental Variable Analysis.
Sign Up to like & getrecommendations! Published in 2021 at "Kidney international"
DOI: 10.1016/j.kint.2021.03.018
Abstract: Inferring causality from observational studies can be challenging because of the perennial threat of biases from selection, measurement, and confounding. The gold standard study design in clinical research is the randomized controlled trial, since random… read more here.

DOI: 10.1016/j.rie.2021.06.002
Abstract: Abstract We examine the effect of the marginal child and the total number of children on self-reported well-being as a proxy for happiness. Prior literature has not controlled for endogeneity. We propose an instrumental variable… read more here.

DOI: 10.1016/j.rse.2019.03.003
Abstract: The global validation of remotely sensed and/or modeled geophysical products is often complicated by a lack of suitable ground observations for comparison. By cross-comparing three independent collocated observations, triple collocation (TC) can solve for geophysical… read more here.

DOI: 10.1017/psrm.2018.61
Abstract: Abstract Instrumental variable (IV) methods are widely used to address endogeneity concerns. Yet, a specific kind of endogeneity – spatial interdependence – is regularly ignored. We show that ignoring spatial interdependence in the outcome results… read more here.
