Transparency in the conduct and reporting of clinical trials is supported by the guidance produced on the content of clinical trial protocols and reporting standards for clinical trials. While the principle features of the statistical analysis are required within this guidance it is generally accepted that a separate Statistical Analysis Plan is also developed as the level of detail appropriate for a SAP is excessive for a protocol. However, there is no detailed guidance on the content of a SAP and consequently, there is marked variation in practice.

Guidelines for the Content of Statistical Analysis Plans in Clinical Trials

by Carrol Gamble

Abstract Importance  While guidance on statistical principles for clinical trials exists, there is an absence of guidance covering the required content of statistical analysis plans (SAPs) to support transparency and reproducibility. Objective  To develop recommendations for a minimum set of items that should be addressed in SAPs for clinical trials, developed with input from statisticians, previous guideline authors, journal editors, regulators, and funders.
