Biostatisticians’ Goals When Working with You

  • Enhance the integrity and validity of your study
  • Ensure the design has strong internal validity and, if possible, external validity
  • Specific aims
  • Measurement quality
  • Sampling plan
  • Randomization procedures
  • Data management
  • Statistical power
  • Appropriate analyses

Start Working with Us Early and Always!

  • Early in proposal development stage is the best
  • Studies have problems, that is OK
    • Definitely consult with a statistician before making changes and hoping for the best
    • If biostatisticians are active collaborators on the project, they can sometimes see trouble ahead and help to prevent or alleviate it
  • Involve us in database design and data management approach
  • We are an important part of the DSMB
  • We love to do complex analyses but in reality that is a very small part of how we spend our time on a project
     
  • Grant Proposals
    • Role of Co-Investigator on the proposal
    • Biostatistician role in proposal development
      • Align aims, methods, and analyses
      • Conduct preliminary study analyses, if needed
      • Conduct power analyses
      • Write the analysis section of proposals
    • Review the budget to ensure support for data management, data cleaning, and analyses
  • Analyses for Manuscripts and Presentations
    • We are able to help depending on the scope of the request
    • Best approach
      • Meet with Nancy Perrin to discuss what is needed, devise analysis plan, and timeline
      • Work will be assigned to a Biostatistics Core member based on interest, expertise, and workload
    • Depending on the amount involvement in the project, the biostatistician may be considered for co-authorship
  • Research Design and Analysis Seminars
    • Monthly seminars
      • Measurement
      • Data Management
      • Mediators and Moderators
      • Adaptive Trials
      • Pragmatic Trials
      • Cluster Randomized Trials
      • Observational Methods
      • PROMIS Measures
    • Considering having mini-courses that go more in-depth on certain topics
      • Possible credit for student
  • Support for Graduate Students
    • PhD NRSA Proposal Support
      • Student works with one Biostatistics Core member on the proposal
      • The Student, Adviser, and Biostatistician reach agreed upon aims, research design, and analysis plan
      • Help with power analyses, writing of the analysis section
      • Need to begin working together at least 45 days prior to the submission date
    • Dissertation
      • Goal is to have students participate in the data management training and working group so they can do their own data management under guidance
      • If analyses are complex, it is recommended a Biostatistics Core member is on the committee
    • Assist in conducting analyses
    • Review reporting of results
      • If no biostatistician on the PhD committee, Biostatistics Core will provide basic consultation
  • Data Management and Post-Award Support
    • Train project staff in data management, data cleaning, and data integrity (TBD)
    • Hold monthly or bimonthly working group of project staff to discuss issues in recruitment, retention, and data management (TBD)
    • Develop a pool of trained and mentored statistical analysts that can be written into grants (NP)
  • Involving Students in Biostatistics Core
    • 3-4 students who have demonstrated experience with data management and data analysis
    • After completing a test project, students are assigned to a project and mentored by a Biostatistician
    • Students and Biostatistics Core meet together to discuss ongoing projects
    • Students may be able to help with analyses of manuscripts and presentations when there is no funding available
    • Could satisfy a Research Residency
