In the public repository, there are two main folders scripts and results. In the program scrips, there is a data directory that is hidden and not included as we no longer have access to data due to data use agreements with Optum.

• scripts: Two sub folders in this folder.

  • analysis: Contains the scripts to fit and test predictive models
  • sql_query: Contains SQL queries and scripts to build the analysis dataframe to use in analyses. Requires Optum license and data cut of IBD patients.

• results: Folder that contains results. See overview in analysis folder for where specific model results are saved.
