The GFS data can be analyzed in any statistical analysis package. We have coordinated analysis scripts for use in R, SAS, SPSS, and Stata. An analysis script provided in the subfolder 'Meta-Analysis Code and Online App/gfs_in_a_single_run.R' can be used to conduct the country-specific analyses and meta-analyze those results simultaneously. The software specific scripts were initially uploaded simultaneously and contained in the .ZIP files: 1. Demographic Variation Code 2024-03-14 2. Childhood Predictors Code 2024-03-15 Since these files were uploaded, updates and fixes to bugs have been made in software specific releases to attempt some version control and identification of which versions were used for which papers/analyses and when. If replicating analyses, please try to use the same version, but for updating analyses we recommend using the most recent script for the specific software and analysis type. The meta-analysis Shiny app (https://gfs-coding-team.shinyapps.io/meta-analysis-shiny-app/) is being continually updated and maintained. Please report any bugs to the primary maintainer R. Noah Padgett (npadgett@hsph.harvard.edu). We welcome any findings of bugs or suggestions for improvements. Data for the GFS is available upon submission of a pre-registration (https://www.cos.io/gfs-access-data).
