R code for meta-analysis

Summary

I don't have enough information to write an accurate summary here—this "paper" is actually just R code (statistical software) attached to a separate study about microplastics affecting iron processes in wetland soils, not a research paper with its own findings to report. If you can share the actual study it's linked to ("Microplastics Reshape Iron Oxidation in Wetlands"), I'd be glad to summarize that instead. Broadly speaking, that kind of research looks at how microplastic pollution disrupts natural chemical cycles in ecosystems like wetlands, which matters because these processes affect water quality and how pollutants move through the environment—
