Developing a Protocol for Observational Comparative Effectiveness Research: A User's Guide

The Observational CER User's Guide serves as a resource for investigators and stakeholders when designing observational comparative effectiveness research (CER) studies, particularly those with findings that are intended to translate into decisions or actions. The User's Guide provides principles for designing research that will inform health care decisions of patients and other stakeholders. Furthermore, it serves as a reference for increasing the transparency of the methods used in a study and standardizing the review of protocols through checklists provided in every chapter.
