Repository: GitHub

Data Type(s): Code

Organism(s): Homo sapiens

Summary: This repository contains the necessary scripts to reproduce the analysis of Bozack et al.'s "Exposure to arsenic at different life-stages and DNA methylation meta-analysis in buccal cells and leukocytes". The organization of the repository is as follows: The bangladesh-study folder contains the scripts and results associated with the Bangladesh DNAm studies. The chile-study directory is made up of subdirectories containing the code and results associated with the buccal cell and the PBMC DNAm analyses. It also holds a directory with notebooks assessing the within-participant buccal-PBMC sample similarities, and a directory with a notebook of descriptive statistics used to create Table 1 in the accompanying paper. The DMR-meta-analysis folder contains the DMR-meta-analysis.Rmd notebook, which details the meta-analysis procedure and summarized the results output by comb-p. The helper-scripts directory contains multiple helper files used to perform the analyses described in the paper.
