The Biostatistics and Clinical Research Core provides state-of-the-art services from conception through completion of a project. Starting with consultation, study design, and data management, the Core then assists with the collection, analysis and integration of biological and epidemiological data. It provides assistance with database implementation and maintenance, web applications, validated and secure data capture, quality control, and statistical analysis. The Core provides an interface between basic scientists, clinical researchers, and informatics specialists to support translational research. Clinical research support includes IRB submission, contract negotiation, regulatory issues, IND, and tissue procurement. The Core maintains access to a set of large administrative databases utilized by members of CGIBD as well as trainees.


  • Consultation on biostatistics and study design during the design, conduct and analysis phases of research.
  • Data collection and data management services including forms development, enrolment tracking, data capture, data validation, data security and confidentiality, database closure, statistical programming, application development.
  • Access to large claims databases such as IMS Pharmetrics, MarketScan and Medicare
  • Clinical research support through regulatory advice, contract negotiations, and data and specimen collection provided by a team of experienced study coordinators.
  • Training and education about sample size and power calculations, study design and analysis.


Core services are performed on a fee-for-service basis. Center members are entitled to 8 hours of the core without charge. The hourly rate for members, non-members and corporate users are listed below.
