Site Selection MethodologySelection of the GRACE study centres was based on scientifically rigorous sampling techniques. Scientific Committee Members, data managers, and outcomes specialists teamed with epidemiologists to develop a population-based model that would accurately reflect healthcare access, practice patterns, and patient volume for each of the various advisor site regions throughout the participating countries. A site selection model to identify prospective sub-sites was developed based on population sample size and feasibility for study. |
