"Walker and Shostak offer a comprehensive introduction to fundamentals, concepts, and applications of statistics in clinical trials. Using data examples from drug development, sample SAS code is provided to help solve problems commonly found in clinical trials. Useful explanations of SAS code are given and common pitfalls are shown.

This book is a good reference for SAS programmers, clinicians, students, and professionals who want to learn SAS applications but may not have either clinical trials experience or statistical course work."
