What is the purpose of a table shell in a statistical analysis plan (SAP)?

The purpose of a table shell in a statistical analysis plan (SAP) is to provide an outline or sketch of a statistical table that is expected to be included in the final analysis. This table shell serves as a blueprint for how the data will be presented—detailing the variables, the format of the output, and the layout of the table. It helps streamline communication among team members and ensures that everyone has a clear understanding of how results will be organized and displayed.

By depicting the structure in advance, the table shell allows for early identification of any necessary modifications to the analysis plan, ensuring that the final tables meet regulatory and reporting standards. This planning aids in reducing errors and helps maintain consistency throughout the statistical reporting process.
