In this QCast episode, Jullia and Tom unpack Statistical Analysis Plans (SAPs) — the blueprints that define how clinical trial data are turned into evidence. They explore what a SAP includes, how it links to the protocol and estimand framework, and the controls that keep analyses credible, reproducible, and inspection-ready. 

Key Takeaways

•  Treat the SAP as the bridge between protocol intent and statistical execution. 
•  Anchor all analyses to the estimand framework to maintain alignment and interpretability. 
•  Finalise and version-control the SAP before data lock to prevent bias and audit issues. 
•  Define derivations, flags, and datasets explicitly to enable traceable, reproducible code. 
•  Keep interim analysis logic clear, with independent oversight and documented firewalls. 
•  Apply disciplined change control and independent quality checks throughout analysis. 
•  Make every method explainable to clinicians — clarity, not complexity, drives confidence.
