WebBayesian kernel machine regression (BKMR) and Quantile-based g-computation (QGC) were used to investigate the association of metal mixture exposure with these outcomes.ResultsIn single metal... WebMar 16, 2024 · The BKMR framework is a flexible nonparametric approach that allows the estimation of the overall effect estimate of multiple correlated exposures accounting for confounding variables. 49 The method was implemented with the R package “bkmr” using 10,000 iterations. 50 All variables were included in the model using the variable selection …

WebWe use BKMR for the mediator and outcome regression models since BKMR allows for all possible nonlinearities and interactions among the elements included in the kernel with the specified outcome, without a prior specification, and credible intervals a BKMR fit inherently control for multiple testing due to the Bayesian nature of the model and the … WebDec 8, 2024 · Namely, the examples below demonstrate use of the package for: 1. Fast estimation of exposure effects under a linear model for quantized exposures for continuous (normal) outcomes 2. Estimating conditional and marginal odds/risk ratios of a mixture effect for binary outcomes 3. graphic design drawing

WebOct 1, 2024 · We fitted separate BKMR models for all indicators of LFTs outcomes based on the model below: Y i = h (Σ D E H P i, M E P i, M i B P i, M B P i, M C O P i, M C N P i, M C P P i, M B z P i) + β z i + e i where Y i is the continuous LFT outcome; h() is the exposure–response function, which can incorporate non-linear relationships and ... WebAug 28, 2024 · BKMR found a positive linear association with furan 2,3,4,7,8-pncdf, suggestive evidence of linear associations with PCBs 126 and 169, and a positive overall effect of the mixture, but no interactions among congeners. Conclusions WebMar 26, 2024 · In this document, we demonstrate how to apply Bayesian kernel machine regression (BKMR) for binary outcomes using the bkmr R package.
