An integral component of successful Clinical and Translational Research is careful study design, appropriate data analysis, and thoughtful interpretation and dissemination of results. Experts within the Research Design, Epidemiology and Biostatistics core of the AI/AN CTR program will provide resources to support these critical components of research that primary investigators themselves often do not have the training and expertise to accomplish alone.
