The Center of Excellence in Oral and Craniofacial Biology
LSU-HSC School of Dentistry Biostatistical Core

The Biostatistical Core was created through funding from COBRE grant P20RR020160 awarded to the Center of Excellence in Oral & Craniofacial Biology at the LSU Health Sciences Center School of Dentistry

The Core provides COBRE PIs and members of the Center with:
  • Consultation on study design, sample size estimation, statistical analysis plan,and research proposal.
  • Assistance in planning study databases and quality control procedures.
  • Statistical analysis of study data, presentation and interpretation of results.
  • Educational services to support investigator development in study design and analysis of research studies.

Core resources are also available to post-graduate dental residents performing research as part of their graduate educational requirements.

What you should bring to your first meeting:
Important items to bring along to your first meeting with us are:
Research proposal or abstract or draft of your manuscript.
Relevant journal papers relating to your topic and any preliminary findings.
Be prepared to discuss in detail your research hypotheses.
If you are coming for data analysis, you will also need an electronic copy of your data (preferably in Excel) on a CD or e-mailed to us before the meeting along with the codebook. A printed example of your data and the codebook are often useful for discussion.

Codebook is a file to describe the data and indicates where and how it can be accessed. It is an indispensable tool for the analysis team. Together with the database, it should provide comprehensive documentation Minimally it should include the following items for each variable: variable name; variable description; variable format (number, data, text); date collected instrument/method of collection; respondent or group; variable location (in database); notes

How to Set Up an Appointment

Office Hours:
Beginning in January, 2008, the statistical core's offices will be open for consultations Wednesday 9:30-4:00 and Friday 12:30-4:00. Pre-scheduling consultations is highly recommended, but walk-ins are welcome depending on consultant availability. Of course, we are available to meet outside these times if scheduling is a problem. Please contact Joe Hagan to determine a mutually convenient time to discuss your project or inquiry.
