Opis

This book will use the new guidance as a framework for developing and implementing comprehensive analysis plans for clinical trials that support the development and approval of medical interventions.

Recenzje

"The purpose of this book, which is to promote an integrated understanding of key concepts throughout the drug development process through an example-based approach, is certainly achieved. It is the holistic approach to planning the analysis and the focus on practical implementation that distinguishes this text from others... Overall, I enjoyed reading this book, which is a holistic and complete work and will be useful for researchers in the medical statistics area."
